Blob Analysis Overview#

This application note explains VisualApplets Blob Analysis designs.

You learn how to use the Blob Analysis operators in combination with other operators in VisualApplets. The examples use the Blob Analysis operators for basic object detection and classification inside the FPGA. A line applet shows the use of the Blob Analysis 1D operator. Furthermore, C++ SDK projects for the given examples are available. They allow an understanding of the interpretation of Blob Analysis results on PC side. (Application Note SAN011)

The following design examples illustrate the use of the VisualApplets blob analysis operators:

  • Simple Blob Analysis Application Including SDK Project for Object Visualization This example uses the Blob Analysis for basic object detection. All detected objects are transferred to the host PC.
  • Using the Blob Analysis for Classification and ROI Selection This example shows the use of the Blob Analysis for object detection and classification inside the FPGA.
  • Blob Analysis 1D This example explains the use of the Blob Analysis 1D operator for endless line scan images.
