Delete watermark / background and set proper size of mass images

Given 2 folders with pictures from spare parts:

1. folder (1305 pictures): Set background to white and remove shadows and numbers/text which is handwritten on the spare parts if there's any. Set image size to 1,5 : 1 ratio and align spare parts to the center. Remove "DSC_XXXX_C_" from image names. If the focus is improper on the image try to sharpen the picture.

2. folder (842 pictures): Set background to white and remove everything but the spare part from the picture (watermark, handwritten text, sticker, logo etc.) Set image size to 1,5 : 1 ratio and align spare parts to the center. Some of these pictures are low quality and should be improved as much as it is possible. For about 30-40% of the images you just have to set the size to proper ratio, nothing else.
