OpticalFlowUtils

Basic operations for handling optical flow vector fields:

• load/save to .flo fileformat¹
• colorflow to visualize the flow field

Example Usage

using OpticalFlowUtils, FileIO, Plots

x = load("input.flo")

plot(colorflow(x))

save("output.flo", x)

User Notes

• loaded flow fields have type Array{Union{Missing, Float32}, 3} with size (2, height, width).
• flow direction is given in the image coordinate system (i.e. first y downwards, the x rightwards) as usual for images.
