Now there's a "frame buffer" parameter that defines how long a blob's location/label will be remembered by the tracker after it has disappeared from the frame.
- Default is 0, meaning no frames of memory (when a blob disappears, it's forgotten). This is the original behavior from previous version. - Value of -1 sets memory to be infinite. When a blob disappears, it's coord/label remains indefinitely. When a new blob appears within that specified distance threshold, the tracker interprets it as that old blob and assigns the old label. - A value of 30-300 (1-10 sec., assuming 30fps) will remember a blob's coord/label for a short amount of time. This may be good if, for example, a person turns sideways and is momentarily too small to register as a blob.
