matlab 橙色字母,改善MATLAB中橙色的檢測

我的任務之一是從16000圖像中檢測蟻羣中的某些顏色。所以，我已經用藍色，粉紅色和綠色做得非常好，但現在我需要改進對橙色的檢測。這對我來說有點棘手，因爲我是圖像處理領域的新手。我舉了一些例子，我做了什麼，我的問題是什麼。改善MATLAB中橙色的檢測

我用了selectPixelsAndGetHSV.m獲得HSV值，並且我用colorDetectHSV .m來檢測具有相同HSV值的像素。 你可以給我任何sugesstion如何改善橙色的檢測，而不是檢測周圍的整個螞蟻和巢？

預先感謝您！

function [K]=colorDetectHSV(RGB, hsvVal, tol)

HSV = rgb2hsv(RGB);

% find the difference between required and real H value:

diffH = abs(HSV(:,:,1) - hsvVal(1));

[M,N,t] = size(RGB);

I1 = zeros(M,N); I2 = zeros(M,N); I3 = zeros(M,N);

T1 = tol(1);

I1(find(diffH < T1)) = 1;

if (length(tol)>1)

% find the difference between required and real S value:

diffS = abs(HSV(:,:,2) - hsvVal(2));

T2 = tol(2);

I2(find(diffS < T2)) = 1;

if (length(tol)>2)

% find the difference between required and real V value:

difV = HSV(:,:,3) - hsvVal(3);

T3 = tol(3);

I3(find(diffS < T3)) = 1;

I = I1.*I2.*I3;

else

I = I1.*I2;

end

else

I = I1;

end

K=~I;
