Sapera Features - For Coreco Imaging 's frame grabbers & embedded vision engines

Sapera Features

	Colour	Complex
	Color space conversion between RGB, YUV to HSV RGB, YUV, HSV split and merge RGB thresholding	Multiply real or complex images Split and merge real and imaginary component of a complex image Generate power spectrum of an image

	Filters	Geometric Transforms
	Low pass ID & 2D High pass ID & 2D Laplacien Convolution 1D & 2D Gaussian Compass - Enhances edges perpendicular to one of eight directions Gradient - Calculates magnitude and phase Line detect Edgedetect	Flip & Rotation - Flip images in horizontally, vertically or transpose X and Y - Rotate image by an arbitrary angle Pan & Scroll Shear X & Y Perspective image wrap Scale, Zoom, and Re-size an image

	Statistics	Morphology
	Calculate basic statistics such as histogram, pixel count, mean mode, variance, and standard deviation Image background Peaks and Projections Calculate angle and distance Normalized cross-correlation	Binary closing, Open, Erosion & Dilation supports 1, 8, or 16-bit binary images Binary median gradient, outline, and rank filters Conditional binary dilation Binary HitOrMiss, Thinning, and Thickening Thinning with Skeleton constraint Gray scale close, open, and dilation Gray scale median filter Localized thresholding using Tophat Kernel

	Point to Point	Segmentation
	Arithmetic operations - Add, Subtract, Multiply, Divide, Absolute subtract Logical operations - AND, OR, XOR User defined expression Equalize and Threshold - Absolute or statistics based adaptive thresholding Add noise - Add random, spike or gaussian noise to the image LUT - Fill & Invert Unary arithmetic operations - Add, Subtract, Multiply, Divide, Absolute subtract, Initialize and image to a constant Unary logical operations - AND, OR, XOR, User defined expression, Shift left, or Shift right with a constant	Blob Analysis Calculates number of Pixels, sum across a line or a column, square of sum across a line or a column, sum of all the pixels in a given region-of-interest Locates left, right, top and bottom edge Center of gravity XY co-ordinate and angle of a centroid Locate major and minor-axis of an ellipse Calculates area of a blob and bounding box Watershed Contours Find edges across a given path AND Features

	Transforms
	FFT - Compute forward and reverse Fast Fourier Transform on a floating point image Hough transform - supports forward and reverse circular and straight transforms on 8 or 16-bit binary images Fast Hadamard - transform compute forward and reverse Fast Hadamard Transform Discrete Cosine Transform (DCT)
