Automatic sedum background images

Question

Image processing

Good people, tell me please, how can I clean and correct the background of images automatically?
The situation is as follows: for the site there are pictures of bouquets, but the background of the images is a little gray, but a white background is needed. I'm not very versed in the intricacies of image processing, maybe the white balance needs to be corrected. How to do this automatically or semi-automatically, there are many photos. Maybe there are plug-ins for PS, or separate utilities?
Here are examples: buket.yugs.ru/images/cms/thumbs/0800e5acb9b0df06a1...
