I am doing a project on stereo vision and for that i need the 2D location of the 4 points in the below image:
I am confused as to how can I detect those points in Matlab. Is there any function for that ?

I dont know abour other test images, for this specific image, you can locate them using morphological image processing (segmentation).

Assuming all your images are approximetly the same do the following:
I = imread('image.png');
J = im2bw(I);
K = bwpropfilt(J, 'Area', [115, 175]);
figure(1)
subplot(1,3,1); imshow(I)
subplot(1,3,2); imshow(J)
subplot(1,3,3); imshow(K)
stats = regionprops(K,'Centroid');
stats.Centroid % This will provide the 2D coordinates
