基于颜色的图像检索 matlab源代码

用matlab实现基于颜色的图像检索，分块直方图方法。希望对你的毕业设计有帮助

function [Hist RGBt] = getImageHists（imageName PLOT）

% read RGB data:
RGB = imread（imageName）;
RGBt = RGB;
RGB = rgb2hsv（RGB）;

% get image size:
[MNttt] = size（RGB）;

range = 0.0:0.1:1.0;

Hist = zeros（length（range）length（range）length（range））;

for （i=1:M）
    for （j=1:N）
%        N1 = histc（RGB（ij1） range）;
%        N2 = histc（RGB（ij2） range）;
%        N3 = histc（RGB（ij3） range）;                
        
%        nn1 = find（N1==1）;
%        nn2 = find（N2==1）;
%        nn3 = find（N3==1）;            
        
        nn1 = round（RGB（ij1） * 10）+1;
        nn2 = round（RGB（ij2） * 10）+1;        
        nn3 = round（RGB（ij3） * 10）+1;
        
        Hist（nn1 nn2 nn3） = Hist（nn1 nn2 nn3） + 1;
        
    end
end

Hist = Hist / （M*N）;
