Based on the matlab core image processing method and system

The present invention relates to image processing technologies, based on MATLAB discloses a core image processing method and system. The method comprising: find changes of color in the pixels in the core the color image to be processed; color channel transformation based on changes of color; Specific methods are: for the red cast, by the function d = mod ((R-B), 255 ) converting color channels; blue for casting, mod ((B-R), 255) converted by the color channel function d =; function by BW = im2bw (d> t) converts the core image into a binary image; wherein, t is a threshold value comparison, BW is the body image data after binarization, im2bw for application to binary image converting color images based on the comparison threshold. The present invention can accurately divided rock structure and pores in the core image, the digital information to provide a basis for modeling and numerical simulation of petrophysical core build.
