pyorc.Frames.edge_detect

Frames.edge_detect(wdw_1=1, wdw_2=2)

Highlight edges of frame intensities, using a band convolution filter.

The filter uses two slightly differently convolved images and computes their difference to detect edges.

Parameters:

• wdw_1 (int, optional) – window size to use for first gaussian blur filter (Default value = 2)

• wdw_2 (int, optional) – stride to use for second gaussian blur filter (Default value = 4)

Returns:

filtered frames (i.e. difference between first and second gaussian convolution)

Return type:

xr.DataArray
