Image

Normalize image inputs and choose color depth settings for computer vision impulses.

The Image block is dedicated to computer vision applications. It normalizes image data, and optionally reduce the color depth.

GitHub repository containing all DSP block code: edgeimpulse/processing-blocks.

Image parameters

• Color depth: Color depth to use (RGB or grayscale)

How does the image block work?

The Image performs normalization, converting each pixel’s channel of the image to a float value between 0 and 1. If Grayscale is selected, each pixel is converted to a single value following the ITU-R BT.601 conversion (Y’ component only).
