Name | Description | ||||||||||
fxgain | This star multiplies the incoming data stream by the parameter "Gain factor" in fixed-point arithmetic. | ||||||||||
fxnl | This star implements a fixed point normalized lattice filter. | ||||||||||
fxnode | Node for fixed point inputs and outputs. | ||||||||||
gain | This star multiplies the incoming data stream by the parameter coefficient, and outputs the resulting data values. | ||||||||||
gauss | This star generates gaussian samples. | ||||||||||
hilbert | Discrete Hilbert Transform | ||||||||||
hold | This star simulates a sample and hold circuit. | ||||||||||
iirfil | This star designs and implements a cascade form IIR digital filter. | ||||||||||
imgaddnoise | Input an image and add the following noise to it: Uniform noise. Gaussian noise. Spike noise. | ||||||||||
imgbreakup | This star inputs an image and creates sub images. The sub images are sequentially output. | ||||||||||
imgbuild | This star inputs a sequence of images and creates a larger image with the inputted images forming subimages from left to right top to bottom. | ||||||||||
imgcalc | Perform a mathematical or logical operation on an image using another image. | ||||||||||
imgcolorsep | This star inputs an image and outputs multiple images representing color components. | ||||||||||
imgcxmag | This star inputs a complex image height*(2*width) and creates a new real image height*width of magnitudes | ||||||||||
imgcxtrl | This star inputs a complex image height*(2*width) and creates a new real image height*width of only the real part | ||||||||||
imgfdct | This star inputs an image and computes the DCT. Note that the input images must be 8x8. | ||||||||||
imgfft | This block inputs an image and computes its forward or inverse FFT. | imgfft | For a forward FFT a real matrix is expected and a complex image is | imgfft | produced. | imgfft | For an inverse FFT a complex image is expected ( possible result of a | imgfft | forward FFT). | imgfft | Complex images store real and imaginary parts as even and odd sample |
imgfilter | Input an image and filter it. The filter kernel is specified. It must be an ASCII file as follows: | ||||||||||
imggen | Generate a rectangular image. | ||||||||||
imghisteq | This star inputs an image and performes an histogram equalization on it. |
