Fallen clear plastic bottle detection

Hello everyone,

I'm currently working on a project for detecting the presence of a fallen clear plastic bottle in a picture. My problem is that I have issues having distinct shapes that I can use to compare with a known pattern. What I obtain are rough shapes of a bottle fractures in multiple pieces. If I use filters to fill in those gaps, I lose the frontier between two bottles.

I did some test with imadjust, histeq, adapthisteq but it only barely helped...

I'm kid of a beginner in MatLAB image processing.

If you have some tips on what filters/tools, feel free to comment below.

Thanks,

Nick

Try this

clc, clear
I1 = imread('111.jpg');
I = rgb2gray(I1);
I2 = edge(I);
I3 = imdilate(I2,true(3,3));
I4 = bwareaopen(~I3,1e4);
subplot(131)
imshow(I)       
title('Gray original')
subplot(132)
imshow(I3)
title({'edge()','imdilate()'})
subplot(133)
imshow(~I4)
title('bwareaopen()')
