Reconfigurable calculation device on flexible neighboring pixels

A reconfigurable computing (1) for image processing, characterized in that it comprises: • a vicinity of calculating matrix (11), generating matching sub-scores between pairs of pixels resulting from a first series of operations configurable via a configuration register (14), • a flexible reduction shaft (12), providing a second set of configurable functions via the configuration register (14), on the pixel neighborhoods configurable via the register (14) configuration, • a scanning matrix (13), performing calculations configurable via the configuration register (14) results from the reduction of flexible shaft (12).
