I want to automatically remove the marked white pixels in attached Figure named as Picture 2. I have also attached an original image with name Picture1. Can anyone please help me in this. I will be very Thank Full to you.

What is it that defines those pixels? How about if you just picked some column, and erased from there to the center of the image, like

[rows, columns, numberOfColorChannels] = size(binaryImage)
binaryImage(:, 50 : round(columns/2), :) = 0;

I don't know if you just want to pick 50 or some other value, basically manually by turning the axis tick marks on and looking at them, or if you can explain somehow how that column could be automatically chosen.

MATLAB: Remove noise from screw image

The screw and the threads are the black thing and the dust is the lighter things on it. I think you are just using the wrong threshold. You can adjust it in imbinarize(), or you can do it interactively with my interactive thresholding app in my File Exchange.

MATLAB: Function to decrease image size

I know it sounds obvious, so you've probably already done it by now, but did you try inverting the number:

function outputImage = ImageDecrease(inputImage, n)
[rows, columns, numberOfColorChannels] = size(inputImage);
fprintf('Input image has %d rows, %d columns, and %d color channels',rows, columns, numberOfColorChannels)
outputImage = imresize(inputImage, 1/n);
[rows, columns, numberOfColorChannels] = size(outputImage);
fprintf('Output image has %d rows, %d columns, and %d color channels',rows, columns, numberOfColorChannels)
end
