Equalizes the histogram of a grayscale image.
This kernel uses Histogram Equalization to modify the values of a grayscale image so that it will automatically have a standardized brightness and contrast.
[Graph] Creates a Histogram Equalization node.
- Parameters
-
[in] | graph | The reference to the graph. |
[in] | input | The grayscale input image in VX_DF_IMAGE_U8 . |
[out] | output | The grayscale output image of type VX_DF_IMAGE_U8 with equalized brightness and contrast. |
- Returns
vx_node
.
- Return values
