I am working on Motion detection using fastcv. I have followed below mention steps in order to create motion detection

step 1. Raw data from the Camera are firstly aligned and convert it to grayscale, and blur it 
    fcvFilterGaussian3x3u8();
 
step 2. Take First Frame.
    
step 3. Compute the absolute difference between the current frame and First frame.
    fcvAbsDiffu8();
 
step 4. convert to thresholded image. 
    fcvFilterThresholdu8();
 
step 5. Dilate the Image.
    fcvFilterDilate3x3u8();
 
6. Draw the Contours.
 
i have complete upto step 5 , getting the output as per the motion detection algorithms, as shown in the below API  i apply the source Image data as pFilteringData and i obtain the Dilate Image data in pDilate. which is perfect as per the algorithm.
                                                       fcvFilterDilate3x3u8( pFilteringData, w, h, pDilate );
 
Now I want to find the contours and draw different color on the white portion of the dilate data, can any one suggest would i proceed , what are the FastCV APIs that i should use and in what order i should use those APIs

Hi

I need to use fastcv motion detection api 
"fcvUpdateMotionHistoryu8s32"

I couldnt find any use case for this api
can u please tell how to use this api and whether this api can be used for the motion detection

Also in the above comment they have used 5 apis for motion detection even.
whether need to follow that or this single api
