|Title:||METHOD RESOLVING BRIGHTNESS INCONSISTENCY BETWEEN CHANNELS|
A method resolving brightness inconsistency between channels comprises the following steps: providing two images, and configuring, at the seam between the two images, a width range, wherein the seam is covered by the configured width range (01); computing the brightness of each column of pixels in the configured width range (02); employing coordinates of each column of pixels in the configured width range as horizontal and vertical coordinates to obtain a pixel set (03); according to an optimal solution of a RANSAC algorithm, fit the pixel set into a straight line, to obtain an optimal solution model of the pixel set (04); and determining, in the optimal solution model, fitted values of all pixels on one side of the seam, and adjusting, according to the fitted values, the brightness of pixels at corresponding locations on the other side of the seam (05). The method can be utilized to automatically compensate for brightness inconsistency between channels, optimizing the resulting image.
