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
