High quality, low bit rate image compression method is one of the key technologies to develop downhole video logging instrument.
高清晰度,低比特率的图像压缩技术是研究井下电视的关键技术之一。
The finished encoder can compress high resolution video in real time, with low bit rate and high image quality.
实验结果表明该编码器可实现高分辨率视频的实时编码,且具有较低的码率和较好的图像质量。
Most of the bit-rate control schemes in video-compression standards are designed for medium and high bit - rate conditions, while do not work well for low bit-rate.
在大多数视频压缩标准中,码率控制方法都是针对中高码率情况而设计的,而在较低码率情况下的工作情况都不够理想。
Based on the MPEG-4 video traffic of low quality and high quality, a hybrid model is presented to capture the frame size at multiple time scales: the change of scene and fluctuation of bit-rate.
