Riesz magnification for baby sleeping does not work #6

Closed Thanh-Binh closed 4 years ago

Thanh-Binh commented 4 years ago

I tested your SW for the video baby sleeping from MIT, but do not see any magnification. Here is my setting parameters: pyramid level = 4 amplification = 50 Cutoff wave length 5 Freq low 0.04, high: 0.4

Moreover, I am interested in understanding why do you use lowpass and highpass filter within riesz pyramid (by building and reconstruction)?

What do you think? Thanks

Hey,

your Cutoff Wavelength is too low. The rule is - the smaller the cutoff wl, the bigger the spatial image features have to be to be amplified.

High- and Lowpass are needed to generate the pyramid, as described in their paper in Sec. 3.2, originating from Simoncelli et al.

Thanks, I Also find out this solution and change the max values from your GUI BR Binh
