Member Function Documentation

create()

static Ptr< FCVMSER > cv::fastcv::FCVMSER::create ( cv::Size imgSize, uint32_t numNeighbors = 4, uint32_t delta = 2, uint32_t minArea = 30, uint32_t maxArea = 14400, float maxVariation = 0.15f, float minDiversity = 0.2f )

static

Creates MSER detector.

Parameters

imgSize	Image size. Image width has to be greater than 50, and image height has to be greater than 5.
numNeighbors	Number of neighbors in contours, can be 4 or 8
delta	Delta to be used in MSER algorithm (the difference in grayscale values within which the region is stable ). Typical value range [0.8 8], typical value 2
minArea	Minimum area (number of pixels) of a mser contour. Typical value range [10 50], typical value 30
maxArea	Maximum area (number of pixels) of a mser contour. Typical value 14400 or 0.25*width*height
maxVariation	Maximum variation in grayscale between 2 levels allowed. Typical value range [0.1 1.0], typical value 0.15
minDiversity	Minimum diversity in grayscale between 2 levels allowed. Typical value range [0.1 1.0], typical value 0.2

Returns

Feature detector object ready for detection

detect() [1/3]

virtual void cv::fastcv::FCVMSER::detect ( InputArray src, std::vector< std::vector< Point > > & contours )

pure virtual

This is an overload for detect() function.

Parameters

src	Source image of type CV_8UC1. Image width has to be greater than 50, and image height has to be greater than 5. Pixels at the image boundary are not processed. If boundary pixels are important for a particular application, please consider padding the input image with dummy pixels of one pixel wide.
contours	Array containing found contours

detect() [2/3]

virtual void cv::fastcv::FCVMSER::detect ( InputArray src, std::vector< std::vector< Point > > & contours, std::vector< cv::Rect > & boundingBoxes )

pure virtual

This is an overload for detect() function.

Parameters

src	Source image of type CV_8UC1. Image width has to be greater than 50, and image height has to be greater than 5. Pixels at the image boundary are not processed. If boundary pixels are important for a particular application, please consider padding the input image with dummy pixels of one pixel wide.
contours	Array containing found contours
boundingBoxes	Array containing bounding boxes of found contours

detect() [3/3]

virtual void cv::fastcv::FCVMSER::detect ( InputArray src, std::vector< std::vector< Point > > & contours, std::vector< cv::Rect > & boundingBoxes, std::vector< ContourData > & contourData )

pure virtual

Runs MSER blob detector on the grayscale image.

Parameters

src	Source image of type CV_8UC1. Image width has to be greater than 50, and image height has to be greater than 5. Pixels at the image boundary are not processed. If boundary pixels are important for a particular application, please consider padding the input image with dummy pixels of one pixel wide.
contours	Array containing found contours
boundingBoxes	Array containing bounding boxes of found contours
contourData	Array containing additional information about found contours
