Dark and Bright Envelopes for Dehazing Images

We present a method for dehazing images. A dark
envelope image is derived with the bilateral minimum filter and a
bright envelope is derived with the bilateral maximum filter. The
ambient light and transmission of the scene are estimated from these
two envelope images. An image without haze is reconstructed from
the estimated ambient light and transmission.
