Some embodiments are directed to a method for correcting a movement trajectory in a movement assistance device of a person equipped with at least one sensor device and a control unit, the method including the steps of measuring a distance between said at least one sensor and an obstacle, a separation of a coordinate system representing pairs of values of translational speeds and rotational speeds into two half-planes, by at least one separating limit of the coordinate system, into a travel exclusion zone and a permissible travel space, a definition of a second rotational speed and a second translational speed by the projection of a command point into the delimited permissible space.

The invention proposes a method for reconstructing a self-similar textured region of an image. Said method comprises determining pixels of a part of the self-similar textured region by copying sample pixels from a sample part of the self-similar textured region, the sample pixels being selected using a neighborhood matching, wherein a size of neighborhoods used for matching is selected based on an analysis of descriptors computed from coefficients of OCT transform of differently sized blocks of the sample part. The analysis of descriptors computed from coefficients of DCT transform of differently sized blocks of the sample part allows for determining the neighborhood size close to a feature size of the texture.
