OpenCV Mat(比较)运算符文档
OpenCV Mat (comparison) operators documentation
您知道在哪里可以找到 cv::Mat 运算符的文档,例如 <
、<=
等吗?我目前的疑问是想知道 <
运算符是否 returns 或 ~0
值(=255
用于 uint8_t 图像,=65535
用于 uint16_t 图片等等)。正在阅读here, it is implied that the expected behaviour is the one given by the equivalent compare 来电。但是我很难在 OpenCV 文档中找到参考。
我试过 google:
opencv mat operator documentation
正确的搜索词是 Matrix Epressions。
来自 OpenCV 2 Documentation:
Comparison: A cmpop B
, A cmpop alpha
, alpha cmpop A
, where cmpop
is
one of : >
, >=
, ==
, !=
, <=
, <
.
The result of comparison is an 8-bit
single channel mask whose elements are set to 255 (if the particular
element or pair of elements satisfy the condition) or 0.
在 OpenCV 3 中,关于矩阵表达式的文档分散在页面 Operations on arrays. There is a collection of Matrix Expression here, but with empty documentation! In particular to know what the <
operator does, one has to check the documentation of cv::compare
:
When the comparison result is true, the corresponding element of
output array is set to 255. The comparison operations can be replaced
with the equivalent matrix expressions:
Mat dst1 = src1 >= src2;
Mat dst2 = src1 < 8;
...
