Abstract
Computerized method for separating an object in a digital image and for performing color change on an object within a digital image. The steps include: obtaining a digital image; receiving a selection of an object within the digital image; selecting a plurality of representative pixels estimated to be within the object; calculating a representative color from the plurality of representative pixels; selecting pixels of the digital image and for each pixel calculating a Euclidian distance to the representative color and, if the Euclidian distance is within a set threshold, identifying the pixel as belonging to the object. For color change, the steps include: generating a plurality of masks, each mask storing different property values of the collection of pixels; selecting a new color; applying the plurality of masks to the new color to generate new image of the object.
