product inside image rez=si

[Lajapathy LP]

I have a few thousand product images with white backgrounds, and the products in the images have different heights. I want to make all the products the same height. 

How to achieve this in Photoshop batch processing?

@Lajapathy LP you need to create an action and then do an Automate-Batch. I did this with my students two weeks ago

The key info is that the action uses the white background values to create a selection or select subject. Image menu, Crop. Automate menu, Fit Image and/or Image menu, Image Size. Possibly Canvas Size to normalise all images to square etc. Then run the action via batch, droplet, image processor script or one of many custom scripts.
