hi
i am trying to process image of particle , but the issue is that i get defocused particle, so is there any method to adjust the focus for these defocused particles or remove them
i need to do image binarization after solving that issue to measure particle properties and trace theri velocity through successive frame
i attached image for binarized

I have an idea:
- Binarize image two times with different threshold
- Separate each blob with bwlabel
- Compare areas of intersected blobs. If A1/A2 < value then delete blob
I = imread('123.png');
I1 = im2bw(I,graythresh(I)-0.3);
I2 = im2bw(I,graythresh(I)+0.0);
subplot(121)
imshow(I)
II = cat(3,I1*0,I2,I1);
subplot(122)
imshow(II)
