In this dissertation, the integer transform, quantization, and deblocking filter are expatiated.
本论文着重对整数变换与量化、去方块滤波做了研究。
The deblocking filter is applied to every macroblock to reduce blocking distortion at low rate, which improves the appearance of the decoded images.
去方块滤波是一种用来去除低码率情况下的每个宏块的块效应,提高了解码图像的外观。
Some improvements on deblocking filter and update step for MCTF were proposed.
改进了运动补偿时域滤波中的更新操作,并引入去块滤波。
Even though the proposed deblocking filter is quite simple, it improves both subjective and objective image quality for various image features.
尽管该设计相对简单,但它无论从主观上还是客观上提高了图像质量。
