Connected Components with VLIB 3_0_1_0

Other Parts Discussed in Thread: TMS320C6455

Hi,

       Recently, I try to use connected components labeling API in VLIB. There are 8 connected components in the test image, but VLIB return numCCs with 20, show in the result image. The CCMap suggest correct result, but components value are 1 2 3 4 5 6 7 20. Is this a bug?

 

test image:

result image:

part of code:

    status = VLIB_packMask32(src, pack, width * height);

    VLIB_calcConnectedComponentsMaxBufferSize(width, height, 32, &maxBytesRequired);

    sizeOfCCHandle =  VLIB_GetSizeOfCCHandle();

    handle = (VLIB_CCHandle *) memalign(32, sizeOfCCHandle);

    pBuf   = (void *)  memalign(32, maxBytesRequired);

    status = VLIB_initConnectedComponentsList(handle, pBuf, maxBytesRequired);

    status = VLIB_createConnectedComponentsList(handle, width, height, (uint32_t *)pack, 32, 1);

    status = VLIB_createCCMap8Bit(handle, dst, width, height);

    VLIB_getNumCCs(handle, &numCCs);
