Check if input changed above threshold (e.g. different image or scene change in video) by Check if input changed above threshold (e.g. different image or scene change in video) by
reducing input (image, video, etc.) to 32x32 grayscale image and run pixel compare with previous input measuring relative pixel difference between last known input and current input averaged by input resolution
If difference is higher than `config.cacheSensitivity` (expressed in range 0..1) then cache is reset If difference is higher than `config.cacheSensitivity` (expressed in range 0..1) then cache is reset
Setting `config.cacheSensitivity=80` disables caching Setting `config.cacheSensitivity=80` disables caching
Caching can be monitored via `human.performance`: Caching can be monitored via `human.performance`:
- `frames`: total number of processed frames - `totalFrames`: total number of processed frames
- `cached`: number of frames considered for caching - `cachedFrames`: number of frames considered for caching
