Convert Image Processing code from JAVA to Python

Need to convert an Image processing code in Java to Python. Nutshell flow in Java: For each image: Read an MBF image Detect faces Get Image bounds based on a keyword Do computation with RGB colors and set 64 parameters. ( Feature Vector) The program will be reading in json documents ( can be easily rendered as json, csv or xml ) We have about 1 Million records containing images as URL links ( one Image per record needs to be processed). The "feature vector" will be a new field ( or a set of fields) that will be added to the original json document. The implementation should be time and space efficient. JAVA implementation will be shared, of course. Please mention "IRPY" at the beginning of your proposal for authentication purposes. Thanks!
