This pull request introduces a new video demo for PRIMA Stage 1 inference and adds a shell script for easy execution. It also improves the renderer to handle image normalization more robustly in full-frame rendering mode. The main changes are grouped below.
New Features:
demo_video.pyscript to perform PRIMA Stage 1 inference on each frame of a video, including Detectron2-based animal detection, rendering options, mesh export, and flexible CLI arguments.demo_video.shshell script as a usage example to run the video demo with default parameters and checkpoint paths.Renderer Improvements:
prima/utils/renderer.pyto handle cases where the input image to the renderer is already a NumPy array (not a file path), ensuring proper normalization to the [0, 1] range for full-frame rendering.
