Returns numpy array of resized image and path where resized file is saved. Note ---- Azure COGS CV has size limit of < 4MB and min size of 50x50 for images. Hence, large image files are being reshaped in code below to increase speed of SHAP explanations and run Azure COGS for image captions. If image (pixel_size, pixel_size) is greater than 500 for either of the dimensions: 1 - image is resized to have max. 500 pixel size for the dimension > 500 2 - other dimension is resized retaining the original aspect ratio N.riTrF)dsizer4zReshaped image size:r*)r2rrsplitshapeintr+resizerr r r/r0r1) r' reshaped_dirr& reshaped_pathr"tail file_name max_pixelsreshapenew_dims r resize_imagerIQs } %EMggmmM*GA 3"IJG {{1~Q'EKKNS,@* Q%++a.
