Isticmaalka iskaanka si loo kaydiyo sawiradii hore waxay noqon kartaa waayo-aragnimo abaal-marin leh. Waxaad keenaysaa sawir-qaadistaagii hore da'dii dhijitaalka ah oo waxaad haysataa fursad aad ku hagaajiso sidoo kale. Software-ka tafatirka sawirka sida Photoshop iyo The Gimp waxay leeyihiin wax badan oo ay bixiyaan, oo ay ku jiraan jeexid, toosin, kor u qaadida midabka midabka iyo dhalaalka, iyo in ka badan. Maqaalkan, waxaan uga hadli doonaa adeegsiga aaladda Xulashada Heal ee The ^{(Heal Selection)}Gimp si aan meesha uga saarno cilladaha yaryar (iyo mararka qaarkood waaweyn), sida xagashada, dhibco ka soo baxa boodhka sariirta iskaanka, iyo ciladaha kale.

Fiiro gaar ah: Waxaad sidoo kale ku isticmaali kartaa qalabkan gudaha Windows, laakiin waxaad u baahan doontaa inaad marka hore rakibto GIMP Resynthesizer plugin . ^{(Note: You can also use this tool in Windows, but you’ll need to first install the GIMP Resynthesizer plugin. )}

Waxa ugu horreeya ee aad u baahan doonto waa sawir aad ku shaqeyso. Tusaalooyinkayaga, waxaan u isticmaali doonaa sawirka daboolka buug ee aan xaqiiqdii ahayn xaalad saafi ah. Si cad ayaa loo akhriyay, jaldiga horena xoogaa dib buu u soo laabtay, taas oo keentay in xariiqda sawirka daboolku ka go'ay, la'aanta erey ka fiican. Halkan waxaa ah meel dhow oo aan isku dayeyno inaan hagaajino.

Waxaa jira dhowr siyaabood oo aan isku dayi karno in aan ku hagaajino cilladahan, sida qalabka smudge, ama innagoo koobiyayna xoogaa midab ah oo u dhigma cilladaha, oo aan ku dhajino meelaha xunxun. Waxaan sidoo kale, si degdeg ah laakiin cayriin u hagaajin, si fudud ugu dhejin karnaa midab ku habboon cilladaha. Sida ku xusan, si kastoy ahaataba, waxaanu isticmaali doonaa qalabka xulashada bogsiinta ee ^{(Heal Selection)}Gimp si aanu u hagaajino daboolka (ugu yaraan intii suurtogal ah).

Gimp - ka waxaa lagu rakibi jiray si caadi ah gudaha Ubuntu , laakiin ma sii ahaanayso, markaa waxaan u baahan doonaa inaan ku rakibno. Waxaad sidaas ku samayn kartaa adiga oo ku dhejinaya sudo apt-get install gimp gimp-plugin-registry kaas oo rakibaya ma aha oo kaliya Gimp , laakiin noocyo badan oo plugins ah, kuwaas oo qalabka Xulashada Heal^{(Heal Selection)} uu ka mid yahay.

Marka si buuxda loo rakibo, horay u soco oo fur Gimp -ga . Waxaan isticmaaleynaa Ubuntu , markaa waxaan ku furi doonaa Dash , laakiin waxaad ku isticmaali kartaa Gimp gudaha Windows oo aad ku bilaabi kartaa adigoo isticmaalaya Start Menu .

Waxaad sidoo kale midig-guji kartaa sawirka, ka dibna dooro GNU Image Manipulation Program (ama waxaa loo yaqaan GIMP ) hoosta Open With menu.

Marka sawirka la shubo, soo dhawaaw sawirka ilaa mid ka mid ah cilladaha uu si sahal ah u muuqanayo. Hadda ku dooro adigoo isticmaalaya mid ka mid ah saddexda qalab ee xulashada.

Kuwa aan aqoon u lahayn Gimp , qalabka bidix ee fog - Qalabka Xulashada leydi -^{(Rectangle Select Tool –)} wuxuu doortaa qaab leydi ah; Midda dhexe waa Qalabka Xulashada Ellipse^{(Ellipse Select Tool)} (oo loogu talagalay wareegyada iyo gobollada kale ee elliptical); Qalabka midigta fog waa Qalab Xulasho^{(Select Tool)} Xor ah kaasoo kuu ogolaanaya inaad qeexdo gobollo sax ah. Waxaan isticmaali doonaa kan. Marka gobolkaaga la doorto, waa inuu u ekaado wax sidan oo kale ah.

Markaad isticmaalayso qalabka xulashada^{(Heal Selection)} bogsiinta, waa inaad doorataa aagag yar yar maaddaama pixels ku hareeraysan ay u badan tahay inay la mid yihiin xulashada, taas oo ka caawinaysa natiijada u muuqata ugu yaraan wax u dhow asalka. Marka aad doorato aaggaaga, si fudud u tag menu-ka Filter - ka, ka dib menu- hoosaadka Enhance , oo ugu dambeyntii dooro aaladda Xulashada bogsiin .^{(Heal Selection)}

Daaqad sidan oo kale ah waa inay soo baxdaa, oo leh xulashooyinka aaladaha.

Waxaa jira saddex ikhtiyaar marka la isticmaalayo xulashada^{(Heal Selection)} bogsiinta. Marka hore^(First) waa tirada pixels ee ku wareegsan xulashadaada qalabku waa inuu ka doorto. Waxa qalabku sameeyo waa in uu qaato pixels-ka ku xeeran, oo isku day in aad isku dhex darto aagga aad dooratay si loo waafajiyo agagaarkeeda. Haddii aagga doorashadaadu ay tahay mid taagan, waxaad kaga tagi kartaa lambarka sida caadiga ah (oo ah 50 pixels), laakiin haddii aad u baahan tahay inaad ka taxaddarto inaadan qalabku u dhigmin meel aad u kala duwan, waxaad yareyn kartaa tirada pixels xisaabta ayay ku jirtaa.

Doorashada labaad ee aad haysato ayaa ah in qalabku ka soo saaro pixels dhammaan agagaarka agagaarka, kor iyo hoos, ama dhinacyada.

Ugu dambeyntii, ikhtiyaarka saddexaad waa sida meesha la doortay loo buuxinayo. Waxaa mar kale jira saddex doorasho. Qalabku wuxuu si aan kala sooc lahayn u dhigi karaa pixels, ama wuxuu buuxin karaa aagga la doortay isagoo ka soo bilaabaya bannaanka oo galaya, ama caksi ahaan, wuxuu ka soo bilaabi karaa gudaha oo ka guuri karaa.

Marka aad dhammayso xulashooyinka, dhagsii badhanka OK . Qalabku waa inuu xoogaa ka fikiraa (waxay kuxirantahay inta uu le'eg yahay aagga la doortay ee aad ka shaqaynayso).

Markaad dhammayso, waxaan rajaynaynaa in aaggu horumaray. Halkan waxaan ku samaynay dhowr sixid.

Hoosta, waxaad ka heli doontaa inaan ka koobnay laba sawir oo aag waxyar ka weyn oo hadda la bedelay ("kahor" iyo "ka dib") si loo muujiyo waxa lagu gaari karo isticmaalka garsoor ee qalabka Xulashada Heal^{(Heal Selection)} . Sida aad arki karto, Qalabka Xulashada Heal^{(Heal Selection)} aad buu u fiican yahay in laga saaro qoraalka iyo calaamadaha (ilaa inta ay jirto meel ku filan oo ku hareeraysan qalabku si aad fikrad uga hesho waxa haddii kale ku jiri lahaa "hoosta" qoraalka ama astaanta).

Taasina aad bay u qurux badan tahay. Tani ma aha qalab hagaajin doona dhibaato kasta dabcan. Ma qiyaasi karto xarfaha maqan yihiin (waa in gees ka mid ah bogga la gooyo), iyo marka ay sii adkaato aagga la doortay, waxay u badan tahay in natiijadu u ekaato wax u dhow asalka. Si kastaba ha noqotee, asal ahaan, xulashooyin dhib yar, iyo xitaa sidii looga takhalusi lahaa maqaarka maqaarka, Qalabka Xulashada Bogsiinta^{(Heal Selection)} waa mid fiican oo la yaqaan. Ku raaxayso!

Erase Scratches in Photos with the GIMP’s Heal Selection Tool

Using a scanner to archivе old photographs can be a rewarding experience. You bring your оld snapshots into the digital agе and have the chance to fix them up aѕ wеll. Image editіng software such as Photoshop and The Gіmp have a lot to offer, including cropping, straightening, enhancing an imageѕ’ color saturation and brightness, and more. Іn this article, we’ll tаlk about uѕing the Heal Selection tool in The Gimp to get rid of minor (and sometimes major) imperfections, such as ѕcratches, spots from dust on the scanner bed, and other blemishes.

Note: You can also use this tool in Windows, but you’ll need to first install the GIMP Resynthesizer plugin. 

The first thing you’ll need is an image to work on. For our examples, we’ll use a cover image from a book that was definitely not in pristine condition. It had obviously been read, and the front cover bent back quite a bit, which resulted in a line where the cover image had flaked off, for lack of a better term. Here is a closeup of an area we’re trying to fix.

There are a number of ways we could attempt to fix these blemishes, such as the smudge tool, or by copying a bit of color that matches the blemish, and pasting it over the bad spots. We could also, for a fast but crude fix, simply paste a matching color into the imperfections. As mentioned, however, we’ll be using the Heal Selection tool in The Gimp to fix the cover (at least as much as possible).

The Gimp used to be installed by default in Ubuntu, but it isn’t any longer, so we’ll need to install it. You can do so by typing sudo apt-get install gimp gimp-plugin-registry which installs not only The Gimp, but a large variety of plugins, of which the Heal Selection tool is one of.

Once fully installed, go ahead and open The Gimp. We’re using Ubuntu, so we’ll open it via the Dash, but you can use The Gimp in Windows and launch it via the Start Menu.

You could also right-click the image, then choose GNU Image Manipulation Program (or it may be called GIMP) under the Open With menu.

Once the image has loaded, zoom into the image until one of the imperfections is readily visible. Now select it using any of the three selection tools.

For those unfamiliar with The Gimp, the far left tool – the Rectangle Select Tool – selects a rectangular shape; the middle one is the Ellipse Select Tool (for circles and other elliptical regions); the far right tool is a Free Select Tool which lets you outline more precise regions. We’ll be using this. When your region is selected, it should look something like this.

When using the Heal Selection tool, you should select small areas as the surrounding pixels are most likely to be similar to the selection, which helps in a result that looks at least somewhat close to the original. Once you’ve selected your area, simply go to the Filter menu, then to the Enhance submenu, and finally select the Heal Selection tool.

A window like this should appear, with the tool options.

There are three options when using the Heal Selection tool. First is the number of pixels surrounding your selection the tool should choose from. What the tool does is take in the surrounding pixels, and attempt to blend in the area you’ve selected to match its surroundings. If the area around your selection is fairly static, you can leave the number at its default (of 50 pixels), but if you need to be careful not to have the tool match a wildly different area, you can shrink the number of pixels it takes into account.

The second option you have is whether the tool samples pixels from the entire surrounding area, just above and below, or from the sides.

Finally, the third option is how the selected area should be filled. There are again three options. The tool can randomly place pixels, or can fill the selected area starting from the outside and going in, or conversely, start from the inside and move out.

Once you’re finished with the options, click the OK button. The tool should think for a bit (depending on how large a selected area you’re working on).

When you’re finished, hopefully the area has improved. Here we’ve made a few corrections.

Below, you’ll find that we’ve composited two images of a slightly larger area than was just modified(“before” and “after”) to show what can be accomplished with judicious use of the Heal Selection tool. As you can see, the Heal Selection tool is quite good for removing text and logos (as long as there is enough room around them for the tool to get some idea of what would have otherwise been “under” the text or logo).

And that’s pretty much it. This isn’t a tool that will fix every problem of course. It can’t guess what letters might be missing (should a corner of a page be torn off), and the more complicated the selected area, the less likely the result will look anything close to the original. However, for backgrounds, less complicated selections, and even for getting rid of blemishes on skin, the Heal Selection tool is a nice one to be familiar with. Enjoy!
