Abstract
本发明涉及有效表示图像以及对图像进行编码的系统和方法，特别是涉及对图像深度图的处理。本发明在对图像进行分段之前，对图像的块进行初始化；对深度图块进行分区或分段；对分区或分段后的深度图块进行边界和块近似；重复上述对深度图块进行分区或分段并对深度图块进行边界和块近似的步骤，直至达到最大数量的分割级别；对边界和块近似后的图像进行压缩，获得压缩后的图像。本发明不是将像素值近似为整个分区的常量，而是使用参数模型(例如多项式)对像素进行建模。这为依赖于不同类型的图像块建模在所需的压缩质量提供了更大的灵活性。这使得所提出的方法能够更准确地近似复杂结构，从而实现更好的压缩质量。为了进一步提高压缩率，应用分层聚类进行分区。这使得分区具有更紧凑地表示方式，因此减少压缩后的数据大小。
