Method for merging image format based on index color

Abstract

A method for combining image based on image format of index color includes making histogram statistics on color of source image and judging whether color number in histogram is less than M or not, using color in histogram as palette for synthetic image and selecting color with minimum color difference in palette used for synthetic image as pixel in each synthetic image as well as using index valueof selected color to realize image combination if it is or otherwise selecting m numbers of colors in histogram and utilizing M-m numbers of colors as palette of synthetic image commonly.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, the present invention relates to a method for combining images based on indexed color image formats. Background technique [0002] Medicine has proved that human beings have the characteristic of "persistence of vision". In other words, after the human eye sees a picture or an object, it will not disappear within 1 / 24 of a second. Using this principle, playing the next picture before a picture disappears will give people a smooth visual change effect. Movies and TV are based on this principle. Animation refers to continuously playing a series of static pictures, and switching to the next static picture after each static picture is displayed for a certain period of time, so as to bring the visual effect of continuous picture changes to the observer. The basic principles of animation are the same as those of film and television, and they are all visual prin...

Problems solved by technology

[0012] However, in the prior art, there is no suitable technical means for how to determine the proportion of the source image palette in the final composite palette and how to select appropriate colors

However, the selection of proportions and colors will greatly affect the final image merging result, so discoloration, color cast, etc. often occur in the image merging of the prior art, making the visual effect very unsatisfactory

[0013] In addition, when the number of source images is relatively large, or the color palettes of the source images are greatly different, the image merging effect of this prior art is very poor

When the palettes of multiple source images are quite different, the color difference of the final synthesized image according to the prior art is relatively large, but the selected color of the synthesized palette cannot express this feature well, which will lead to some pixels being blurred. The index color is too different from the real color, and the human eye is more sensitive to this pixel, so the visual effect is poor
