Employing automatic content recognition for teaching methodology analysis in classroom videos
Fig 5
This figure illustrates 3DCNN.
The rectangle on top depicts slices of video frames and each slice is an image that is color coded. Contiguous frames convolve with a 3D kernel and it is depicted with regular and dashed lines. The rectangle at the bottom is a depiction of the 3D convolution of image tensor with kernel tensor (it should not be confused with the shared filters).
