Convert Opencv Mat to C# Bitmap

Conversion from Opencv Mat to C# bitmap isn't a difficult task. But this conversion needs to be done from the primitive level of both Opencv Mat and C# Bitmap. Simply all the images are created from set of bytes, therefore it is necessary to create System.Drawing.Bitmat from bytes of cv::Mat. Also you will need to do this conversion...

Convert C# Bitmap to Opencv Mat

Conversion from C# bitmap to Opencv Mat isn't a difficult task. But this conversion needs to be done from the primitive level of both Opencv Mat and C# Bitmap. Simply all the images are created from set of bytes, therefore it is necessary to create cv::Mat from bytes of System.Drawing.Bitmat. Also you will need to do this conversion in...

OpenCV Filters - dilate

Dilates an image by using a specific structuring element. C++: void dilate(InputArray src, OutputArray dst, InputArray kernel, Point anchor=Point(-1,-1), int iterations=1, int borderType=BORDER_CONSTANT, const Scalar& borderValue=morphologyDefaultBorderValue() ) Python: cv2.dilate(src, kernel[, dst[, anchor[, iterations[, borderType[,...

OpenCV Filters - copyMakeBorder

Forms a border around an image. C++: void copyMakeBorder(InputArray src, OutputArray dst, int top, int bottom, int left, int right, int borderType, const Scalar& value=Scalar() ) Python: cv2.copyMakeBorder(src, top, bottom, left, right, borderType[, dst[, value]]) → dst C: void cvCopyMakeBorder(const CvArr* src, CvArr* dst, CvPoint...

OpenCV Filters - boxFilter

Blurs an image using the box filter. C++: void boxFilter(InputArray src, OutputArray dst, int ddepth, Size ksize, Point anchor=Point(-1,-1), bool normalize=true, int borderType=BORDER_DEFAULT ) Python: cv2.boxFilter(src, ddepth, ksize[, dst[, anchor[, normalize[, borderType]]]]) → dst Parameters: src – input image. dst – output image...

OpenCV Filters - buildPyramid

Constructs the Gaussian pyramid for an image. C++: void buildPyramid(InputArray src, OutputArrayOfArrays dst, int maxlevel, int borderType=BORDER_DEFAULT ) Parameters: src – Source image. Check pyrDown() for the list of supported types. dst – Destination vector of maxlevel+1 images of the same type as src . dst[0] will be the...

OpenCV Filters - bilateralFilter

Applies the bilateral filter to an image. C++: void blur(InputArray src, OutputArray dst, Size ksize, Point anchor=Point(-1,-1), int borderType=BORDER_DEFAULT ) Python: cv2.blur(src, ksize[, dst[, anchor[, borderType]]]) → dst Parameters: src – Source 8-bit or floating-point, 1-channel or 3-channel image. dst – Destination...

OpenCV Filters - Blur

Blurs an image using the normalized box filter. C++: void blur(InputArray src, OutputArray dst, Size ksize, Point anchor=Point(-1,-1), int borderType=BORDER_DEFAULT ) Python: cv2.blur(src, ksize[, dst[, anchor[, borderType]]]) → dst dgdfg Parameters: src – input image; it can have any number of channels, which are processed independently,...

OpenCV Filters - adaptiveBilateralFilter

Applies the adaptive bilateral filter to an image. C++: void adaptiveBilateralFilter(InputArray src, OutputArray dst, Size ksize, double sigmaSpace, double maxSigmaColor=20.0, Point anchor=Point(-1, -1), int borderType=BORDER_DEFAULT ) Python: cv2.adaptiveBilateralFilter(src, ksize, sigmaSpace[, dst[, maxSigmaColor[, anchor[, borderType]]]])...

Call OpenCV functions from C#.net (Bitmap to Mat and Mat to Bitmap)

This is the second article of the article series which provide answers to following question! How to call OpenCV functions from C#.net or VB.net. Specially this article describes, how to pass System.Drawing.Bitmap to OpenCV and get a resultant image as System.Drawing.Bitmap from OpenCV. Note that System.Drawing.Bitmap is the class type...
