| 摘 要： | 图像错误隐藏是近年来多媒体传输和错误控制领域研究的热点之一。该文提出了一种新的自适应图像错误隐藏算法。它根据受损图像特征将图像块分为平滑块、纹理块和边缘块,分别采用相应的块恢复技术进行错误隐藏。实验结果表明这种方法能达到满意的错误隐藏效果。

| Abstract: | Error concealment in image communications is becoming increasingly important because of the growing inter-est in image delivery over unreliable channels such as wireless networks.In this paper,a novel adaptive error conceal-ment technique is proposed to enhance the damaged image.This method does classification based on the feature of im-age block and then adaptively selects corresponding algorithm to conceal the errors.The result demonstrates the fine ef-fect of the method. |
