Dear NXP Technical team,
I bought the S32V234-EVB2 (Full EVB) and tried Vision SDK demo as a first try.
Because I have not had enough knowledge about S32V and Vision SDK demo, could you let me ask about the simple algorithm of following demonstration?
(Please refer VisionSDK_S32V2_RTM_1_3_0_UserGuide.pdf ?)
- apps/pex_isp_face_detection_cv
When the faces are detected, the boundering box appear with the several colors (blue, light blue, green, yellow and red)
What does these color mean?
As long as I tested, the blue, light blue and green boxes appear well.
- apexcv_camdisp
The descriptin of this demo is mentioned as blow in the “Description” of the Vision SDK user Guide.
“Application with camera input and display, using APEX-CV functions to invert a color channel depending on the intensity in the green channel.”
Could you give me more explanation about the sentence “to invert a color channel depending on the intensity in the green channel.”?
I’m not clear why the color changes according to the object.
Best Regards,
Naomi Nomura
