摘要:
Disclosed herein are image color matching and equalization devices and related methods. According to an aspect, a method may include determining overlapping portions of a scene within first and second images of the scene. The method may include generating an array of color channel differences between the overlapping portions. Further, the method may include applying a quantization technique to the array of color channel differences for creating a sparse difference color matrix. The method may also include identifying empty locations of the sparse matrix and computing interpolated difference color values to fill them. Further, the method may include modifying the color of at least one pixel of one of the images by performing an inverse look-up in the sparse table utilizing its color, identifying the color difference on the corresponding entry, and applying the color difference on the target pixel.
