TDA4VM: Maximum class number of semantic segmentation visualization in Vision Apps.

Part Number: TDA4VM


Hi, I notice that there is a maximum visualization number declaration in $(PSDK_RTOS)/vision_apps/kernels/img_proc/include/TI/tivx_img_proc_kernels.h, Line 185,

/*For semantic segmentation supported maximum class is 5 including background*/
/*For depth tensor output is U08, which makes for each value one different color has to be assigned,
so each value is treated as different class*/
#define TIVX_PIXEL_VIZ_MAX_CLASS (256U)
, which is used by $(PSDK_RTOS)/vision_apps/apps/dl_demos/app_tidl_seg.
Why the vision_apps only support 5 classes for semantic segmentation visualization? Is there something hardware limitation? Could I visualize more than 5 classes in my segmentation application?
Thanks.
