Abstract
A method, codec device, and system on chip (SoC) are provided for coding a region of interest (ROI) object of a frame. A current frame, which includes the ROI object is received, and a type of the current frame is determined. A complexity of the current frame is estimated. An ROI control signal is generated for controlling ROI coding of the ROI object based on the complexity.
