Functions | |
void | Canny (InputArray _src, OutputArray _dst, int lowThreshold, int highThreshold, int apertureSize=3, bool L2gradient=false) |
Canny edge detector applied to a 8 bit grayscale image. | |
void | fcvdspdeinit () |
Deinitializes the FastCV DSP environment. | |
int | fcvdspinit () |
Initializes the FastCV DSP environment. | |
void | FFT (InputArray src, OutputArray dst) |
Computes the 1D or 2D Fast Fourier Transform of a real valued matrix. For the 2D case, the width and height of the input and output matrix must be powers of 2. For the 1D case, the height of the matrices must be 1, while the width must be a power of 2. | |
void | filter2D (InputArray _src, OutputArray _dst, int ddepth, InputArray _kernel) |
Filter an image with non-separable kernel. | |
void | IFFT (InputArray src, OutputArray dst) |
Computes the 1D or 2D Inverse Fast Fourier Transform of a complex valued matrix. For the 2D case, The width and height of the input and output matrix must be powers of 2. For the 1D case, the height of the matrices must be 1, while the width must be a power of 2. | |
void | sumOfAbsoluteDiffs (cv::InputArray _patch, cv::InputArray _src, cv::OutputArray _dst) |
Sum of absolute differences of an image against an 8x8 template. | |
void | thresholdOtsu (InputArray _src, OutputArray _dst, bool type) |
Binarizes a grayscale image using Otsu's method. Sets the pixel to max(255) if it's value is greater than the threshold; else, set the pixel to min(0). The threshold is searched that minimizes the intra-class variance (the variance within the class). | |
