Please explain, what you have done so far and if you e.g. work with the image processing toolbox.

I already know how to extract the purple.Now how to remove this purple cell from the original image(in grayscale or rgb or other color)

TQ

%% Reading in the image

myImage = imread('B1.jpg');

figure

imshow(myImage)

%% Extracting the blue plane

bPlane = myImage(:,:,3) - 0.56*(myImage(:,:,1)) - 0.56*(myImage(:,:,2));

figure

imshow(bPlane)

%% Extract out purple cells

figure

BW = bPlane > 23;

imshow(BW)

%% Remove noise 180 pixels or less

BW2 = bwareaopen(BW, 180);

imshow(BW2)

This can be done if you adapt one of my color segmentation demos: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

i still can remove the purple one because it surrounding with red and the purple color just inside the red cell(bigger cell) where i want to remove.
