I improved the overall quality and efficiency of the video anonymization system. I updated detection intervals to use the video’s frame rate instead of relying on a hard coded number of frames. This allows the system to adapt well to videos with different frame rates.
I also evaluated several object tracking algorithms, including DaSiamRPN, to find a good one that balances accuracy and speed. After comparing the performance of a bunch of them, I switched to Nano Tracker which was faster than my original KCF and CSRT trackers while being more accurate.
I made additional improvements to privacy by removing metadata from exported videos. I am now also applying EXIF orientation before processing ensuring that images taken from different devices are processed in their correct orientation.
Next, I plan to introduce different anonymization modes like blur and solid black boxes.
