def filter_frame(motion_frame, filtertype, thresh, kernel_size):

Applies a threshold filter and then a median filter (of kernel_sizexkernel_size) to an image or videoframe.

Arguments

  • motion_frame np.array(uint8) - Input motion image.
  • filtertype str - 'Regular' turns all values below thresh to 0. 'Binary' turns all values below thresh to 0, above thresh to 1. 'Blob' removes individual pixels with erosion method.
  • thresh float - A number in the range of 0 to 1. Eliminates pixel values less than given threshold.
  • kernel_size int - Size of structuring element.

Returns

  • np.array(uint8) - The filtered frame.
