Method for reconstructing an image

A method for constructing an image, the method to be implemented using a processor of an electronic device and comprising steps of:

• a) obtaining an original image;
• b) defining a foreground area that is associated with an object in the original image;
• c) identifying a plurality of contour points that define a contour of the object;
• d) for each of the plurality of contour points, obtaining a reference contour point set that includes, on each of two sides of the contour points, at least one reference contour point which is another one of the plurality of contour points;
• e) obtaining a plurality of characteristic lines, each of the characteristic lines being defined by an end point obtained from the contour points, is associated with the corresponding reference contour point set, and has a pre-defined length and a predetermined width;
• f) obtaining, for each of the characteristic lines, a plurality of pixel value sets that correspond respectively with the a plurality of pixels on the original image that constitute the characteristic line;
• and
• g) rearranging the characteristic lines by aligning the end points on one side to form a straight edge and making the characteristic lines adjoin each other side by side, so as to construct a reconstructed image.
