The Research of Feature Extraction Method of Liver Pathological Image Based on Multispatial Mapping and Statistical Properties

Algorithm 1

ACHLAC feature extraction.

Input: Liver pathological image

Output: ACHLAC features

Steps:

()    Traverse the pixel of the whole pathological image, and calculate the Average of the gray value;

()    Traverse the pixel of the whole pathological image, and calculate , then update every pixel value;

()    Traverse each pixel after updating;

()    for = 1 : 25

()     Local autocorrelation matching using template , then calculate and update the corresponding value ;

()    end for

()    calculate max = ;

()    for = 1 : 25

()     ;

() end for
