Enumeration Type Documentation

anonymous enum

anonymous enum

#include <opencv2/photo.hpp>

Function Documentation

detailEnhance()

void cv::detailEnhance	(	InputArray	src,
		OutputArray	dst,
		float	sigma_s = 10,
		float	sigma_r = 0.15f
	)

#include <opencv2/photo.hpp>

This filter enhances the details of a particular image.

Parameters

src	Input 8-bit 3-channel image.
dst	Output image with the same size and type as src.
sigma_s	Range between 0 to 200.
sigma_r	Range between 0 to 1.

edgePreservingFilter()

void cv::edgePreservingFilter	(	InputArray	src,
		OutputArray	dst,
		int	flags = 1,
		float	sigma_s = 60,
		float	sigma_r = 0.4f
	)

#include <opencv2/photo.hpp>

Filtering is the fundamental operation in image and video processing. Edge-preserving smoothing filters are used in many different applications [EM11] .

Parameters

src	Input 8-bit 3-channel image.
dst	Output 8-bit 3-channel image.
flags	Edge preserving filters: cv::RECURS_FILTER or cv::NORMCONV_FILTER
sigma_s	Range between 0 to 200.
sigma_r	Range between 0 to 1.

pencilSketch()

void cv::pencilSketch	(	InputArray	src,
		OutputArray	dst1,
		OutputArray	dst2,
		float	sigma_s = 60,
		float	sigma_r = 0.07f,
		float	shade_factor = 0.02f
	)

#include <opencv2/photo.hpp>

Pencil-like non-photorealistic line drawing.

Parameters

src	Input 8-bit 3-channel image.
dst1	Output 8-bit 1-channel image.
dst2	Output image with the same size and type as src.
sigma_s	Range between 0 to 200.
sigma_r	Range between 0 to 1.
shade_factor	Range between 0 to 0.1.

stylization()

void cv::stylization	(	InputArray	src,
		OutputArray	dst,
		float	sigma_s = 60,
		float	sigma_r = 0.45f
	)

#include <opencv2/photo.hpp>

Stylization aims to produce digital imagery with a wide variety of effects not focused on photorealism. Edge-aware filters are ideal for stylization, as they can abstract regions of low contrast while preserving, or enhancing, high-contrast features.

Parameters

src	Input 8-bit 3-channel image.
dst	Output image with the same size and type as src.
sigma_s	Range between 0 to 200.
sigma_r	Range between 0 to 1.
