We want to identify software tool/s to alter a human photo programmatically in the constraints of given parameters and criteria. For a given photo, parameters such as height,weight,sex,activity level etc. we want the tool to algorithmically show progression of the body profile change.
As an example, given an individual weighing 300 lb, we want to change the body profile in progression how it would change when the weight is reduced to 250, 200, 150 and 100 lb. We also want similar gradual progression in muscle building.
