Demonstrates a workflow for accelerating a pixel-stream video processing algorithm using MATLAB Coder™ and generating HDL code from the design. You must have a MATLAB Coder license to run
Modify the generated FPGA-in-the-loop (FIL) model for more efficient simulation of the Vision HDL Toolbox™ streaming video protocol.
Demonstrates how to develop a complex pixel-stream video processing algorithm, accelerate its simulation using MATLAB Coder™, and generate HDL code from the design. The algorithm
Demonstrates how to detect and highlight object edges in a video stream. The behavior of the pixel-stream Sobel Edge Detector, video stream alignment, and overlay, is verified by comparing
Convert a pixel stream from R'G'B' color space to Y'CbCr 4:2:2 color space.
Creates the negative of an image by looking up the opposite pixel values in a table.
Use the Image Statistics block to perform multi-zone metering to extract a region of interest (ROI).
Demonstrates a workflow for designing pixel-stream video processing algorithms using Vision HDL Toolbox™ in the MATLAB® environment and generating HDL code from the design.
Extends the cartooning example to include calculating a centroid and overlaying a centroid marker and text label on detected potholes.
Design and implement a separable image filter, which uses fewer hardware resources than a traditional 2-D image filter.
Generate cartoon lines and overlay them onto an image.
Use the Vision HDL Toolbox Histogram library block to implement histogram equalization.
Implement a front-end module of an image processing design. This front-end module removes noise and sharpens the image to provide a better initial condition for the subsequent processing.
Use the Line Buffer block to extract neighborhoods from an image for further processing. The model constructs a separable Gaussian filter.
Model pixel-streaming gamma correction for hardware designs. The model compares the results from the Vision HDL Toolbox™ Gamma Corrector block with the results generated by the
Perform corner detection using the features-from-accelerated-segment test (FAST) algorithm. This algorithm is an alternative to the docid:visionhdl_examples#example-ex91098357
