Detect upsampling in images

In plain words

Resdet is a tool that identifies the original resolution of upscaled images and videos. It analyzes upsampled content to determine what the source resolution was before enlargement. The software is useful for anyone working with digital media who needs to understand the actual quality and original dimensions of scaled images or video files. It's available as an open-source project on GitHub.
