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

Description

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

Ports

Input

Input — 2-D input matrix

2-D matrix

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

Output — Dilated matrix

matrix

Dilated matrix contains the result of 2-D grayscale dilation 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.

Kernel size — Size of structuring element

3x3 (default) | 5x5 | 7x7

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

Extended Capabilities
