 ### Check if caching is allowed
 
 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  
 Setting `config.cacheSensitivity=80` disables caching  
 
 Caching can be monitored via `human.performance`:
-- `frames`: total number of processed frames
-- `cached`: number of frames considered for caching
+- `totalFrames`: total number of processed frames
+- `cachedFrames`: number of frames considered for caching
