How to develop an application that recognize a type of image : i must develop a program in python that recognize the flowchart image files.Result must be 'yes this is a flowchart' or 'no this is not a flowchart'.I have watched a video series that classify dog and cat images, there are two categories as dataset dogs and cats.But i have only one category 'flowcharts'.How can i seperate flowchart images from all other things?
