Ticket Name: Integrating Vision Algorithm on Vision SDK TDA3
Query Text:
Other Parts Discussed in Thread: TDA2 In our project, we have algorithm for vision algorithm for adas camera monitoring system using in c. Which is already working in TDA2 EVM board. I need to integrated with framework which is based on Vision SDK provided by Texas Intruments. To under stand Vision SDK completely,i would like to do Image Negative. I have attached the image which was generated by VSDK user case generation Using user case generation, i have generated file adasens_issImageNegative_priv.c adasens_issImageNegative_priv.h My image negative input, output structure and function prototype are below. typedef struct { unsigned char *ptImageInput; //Input Image to unsigned int uiNoRows; unsigned int uiNoCols; }stImageNegativeInput; chains_vipSingleCameraEdgeDetection.c /*

Responses:
Hi, Algorithm is integrated into Algorithm Link in Vision SDK. You have to create an algorithm link plug-in for your algorithm. Please refer to Chapter 4 in Vision SDK Development Guide. For example, you can refer to ~\VISION_SDK_02_xx_xx_xx\vision_sdk\examples\tda2xx\src\alg_plugins\edgedetection.
