Abstract

The invention discloses a video coding method and equipment on basis of regions of interest. The video coding method includes an object detection step, wherein specified objects in input video frames are detected, and regions of interest and regions of no interest in the video frames are identified on the basis of the detected specified objects; a quantization parameter calculation step, wherein quantization parameter values of macro blocks in the identified regions of interest and regions of no interest are calculated; a macro block type selection step, wherein types of the macro blocks in the regions of interest and regions of no interest are selected on the basis of types of the video frames; a video coding step, wherein the video frames are coded on the basis of the calculated quantization parameter values of the macro blocks in the regions of interest and regions of no interest and the selected types of the macro blocks. According to the method and equipment, video compression can be achieved simply and efficiently, high resolution of the regions of interest is guaranteed, and meanwhile the regions of no interest cannot be too fuzzy to be distinguished.

Description

technical field [0001] The present disclosure relates to video processing technologies, and more specifically, to a region-of-interest (ROI)-based video coding method and device, which can simply and efficiently realize video compression and maintain video frames Good video quality in the ROI area, while not making the video image of the non-ROI area too blurred to be resolved. Background technique [0002] In recent years, applications based on intelligent video processing have been widely used in various electronic devices, and most applications need to transmit compressed video to back-end servers or other communication terminals for further processing. Therefore, there is a problem of conflict between high requirements for video resolution and limited network bandwidth that limits video quality, and a new video encoding method is required to solve this conflict. [0003] Therefore, the concept of ROI is proposed in the video processing technology, so that the applicatio...
