image - 什么是图像处理中的稀疏性？

Question

我是图像处理的新手，不知道基本术语的使用，我知道稀疏的基本定义，但是谁能详细说明图像处理方面的定义？

Answer 1

好吧，Sajid，几个月前我实际上正在做图像处理，我发现一个网站给了我我认为是稀疏性的最佳定义。

Sparsity and density are terms used to describe the percentage of cells in a database table that are not populated and populated, respectively. The sum of the sparsity and density should equal 100%.

A table that is 10% dense has 10% of its cells populated with non-zero values. It is therefore 90% sparse – meaning that 90% of its cells are either not filled with data or are zeros.

我在黑白图像处理的开/关背景下进行了此操作。如果很多像素都关闭了，那么像素就是稀疏的。
