Hello Keerthi,
I understand that you are tyring white blood cell (WBC) classification using Convolutional Neural Networks (CNN), For this preprocessing the images is an important step to improve the performance of your model. Here's how you can perform the three main image enhancement processes you mentioned using MATLAB:
% Read the image
wbcImage = imread('wbc.jpg');
wbcImage = rgb2gray(wbcImage);
% Noise removal with Gaussian filter
filteredImage = imgaussfilt(wbcImage, 2);
% Contrast adjustment
contrastAdjusted = imadjust(filteredImage);
% Image sharpening with unsharp mask
sharpenedImage = imsharpen(contrastAdjusted, 'Radius', 2, 'Amount', 1);
% Display the original and enhanced images
subplot(1, 2, 1);
imshow(wbcImage);
title('Original Image');
subplot(1, 2, 2);
imshow(sharpenedImage);
title('Enhanced Image');
Output:
I hope it helps!
