The vision pipeline reference designs show how complex vision pipelines can be constructed from basic vision kernel building blocks. Those building blocks can be found in aie_kernels/aie2 and contain example kernels written for AI engines in both scalar and unoptimized vector format.
| Design name | Data type | Description |
|---|---|---|
| Vision Passthrough | i8 | A simple pipeline with just one passThrough kernel. This pipeline mainly aims to test whether the data movement works correctly to copy a greyscale image. |
| Color Detect | i32 | This multi-kernel, multi-core pipeline detects colors in an RGBA image. The design consists of the following blocks arranged in a pipeline fashion for the detecting of 2 colors in a sequence of images : rgba2hue, threshold, threshold, bitwiseOR, gray2rgba, bitwiseAND. |
| Edge Detect | i32 | A multi-kernel, multi-core pipeline that detects edges in an image and overlays the detection on the original image. The design consists of the following blocks arranged in a pipeline fashion for the detection of edges in a sequence of images: rgba2gray, filter2D, threshold, gray2rgba, addWeighted. |
| Color Threshold | i32 | A multi-core data-parallel implementation of color thresholding of a RGBA image. The design consists of 4 threshold blocks in separate tiles that process a different region of an input image. The results are then merged back together and sent to the output. |
