I am currently working on a research project involving visual object perception and I am interested in looking at the dorsal stream via EEG task. However I am having issues finding a stimuli. I am in need for fragmented images (ideally 7-8 levels of fragmentation) or a software/code (MATLAB ideally) so I could create the levels of fragmentation myself. Although I do have standardised Snodgrass' set of objects I need to find an efficient way to fragment pictures myself or perhaps find a database from which I could purchase fragmented images. Therefore I wonder if anyone could help me? I would greatly appreciate it. Thank you so much.
