In this talk I shall first present some recent developments in p-harmonic map heat flow into spheres, in particular, for 1-harmonic map heat flow. The highlight of the developments is the BV (bounded variation) solution theory for the flow, which will be reviewed in detail. I shall then discuss the extension of these results to heat flow of a class of linear growth maps. Finally, applications (and their numerical approximations) of these geometric flows to color image denoising based on the chromaticity and brightness decomposition will also be discussed.
