The FPEG (Faces JPEG) technique uses a face detection API to compress the background regions of an image less than the surrounding pixels, resulting in smaller images with comparable perceived quality. This script demonstrates how to use the RapidAPI Face Detection API to reduce the size of facial images while maintaining their resolution. The script takes an image URL as input and applies the FPEG technique to it, reducing its size by compressing the background regions less than the surrounding pixels. The resulting image is saved as "output.jpg". The script also includes error handling and output statistics for verification purposes.
