PPT-Fast Background Subtraction using CUDA

Janaka CDA 6938 What is Background Subtraction Identify foreground pixels Preprocessing step for most vision algorithms Applications Vehicle Speed Computation from Video Why is it Hard Naïve Method . Owens University of California Davis One Shields Avenue Davis CA 95616 pmuyan jowens ucdavisedu Junyi Xia Sanjiv S Samant University of Florida Gainesville FL 32611 junyixia samant u64258edu Abstract In the medical imaging 64257eld we need fast defo Basically a child CUDA Kernel can be called from within a parent CUDA kernel and then optionally synchronize on the completion of that child CUDA Kernel The parent CUDA kernel can consume the output produced from the child CUDA Kernel all withou t heterogeneous programming.
