Abstract :
Differential methods for optic flow estimation suffer from some well know theoretical and practical limitations such as the "aperture problem", sensitivity to noise, intensity discontinuity, etc. This paper presents a new locally robust method to solve the optic flow constraint (OFC). Here, the OFC is formulated as a robust linear regression problem resolved by support vector machines. Outliers are automatically identified as support vectors and are removed with a gradually decreased insensitive e-margin. The performance of our approach is studied and compared with other recent methods.
