We present the novel cloud tracking method developed to estimate horizontal winds from the images obtained by the Venus orbiter Akatsuki. The method is derived from a general consideration, and it is expected to have broad application. This presentation is based on the following papers:

Ikegawa, S., and T. Horinouchi (2016) Improved automatic estimation of winds at the cloud top of Venus using superposition of cross-correlation surfaces. Icarus, 271, 98-119.
