srcFiles=dir('C:\Users\om\Desktop\research\*.jpg');
for i=1: length(srcFiles);
filename=strcat('C:\Users\om\Desktop\research\',srcFiles(i).name);
figure;
i=imread(filename);
imshow(filename);
red=i(:,:,1); green=i(:,:,2); blue=i(:,:,3);
imshow(red);
imshow(green);
imshow(blue);
if(out == red>88 & red<111 & green >86 & green <104 & blue> 73 & blue<97);

Something is wrong with your condition, "out" is undefined.
You can write
if(red>88 & red<111 & green >86 & green <104 & blue> 73 & blue<97);
imwrite(i,'C:\Users\om\Desktop\images\filename.jpg','jpg');
end
But the condition will be true if all pixels in the image fullfil the conditions, i.e., all pixels in the red channel are between 88 and 111, and all pixels in the green channels are between 86 and 104, and all in the blue channel between 73 and 97. If that is what you want, this code works.
If you want something else, please let us know.
