  • HVX erode block with an input port and output port

Libraries:
Embedded Coder Support Package for Qualcomm Hexagon Processors / IPCV

Description

The HVX Erode block performs a two-dimensional (2-D) grayscale erosion on the input matrix using a square structuring element for Hexagon® Vector eXtension (HVX).

Ports

Input

expand all

2-D input matrix whose width is a multiple of 128. The height of the matrix must be greater than or equal to the mask size.

Data Types: uint8

Output

expand all

Eroded matrix contains the result of the 2-D erosion on the input matrix.

Data Types: uint8

Parameters

To edit block parameters interactively, use the Property Inspector. From the Simulink® Toolstrip, on the Simulation tab, in the Prepare gallery, select Property Inspector.

Specify the size of the structuring element for dilation. Larger sizes increase the extent of dilation. Specify the size of structuring element as one of these:

  • 3x3

  • 5x5

  • 7x7
