FIELD: information technology.
SUBSTANCE: invention relates to object recognition and can be used in computer vision systems during image pre-processing. In the device for detecting contours of objects comprising an image sensor, unit for selecting horizontal and vertical pulses, analogue-to-digital converter, generator, digital signal processor, random access memory, there is also a selector, filter unit, spatial differentiation unit, buffer memory for the filter unit, buffer memory for the spatial differentiation unit, connected to each other as indicated in the formula of invention. Faster operation is achieved due to hardware implementation of filtering and spatial differentiation operations in corresponding units of the device.
EFFECT: faster detection of contours of objects on an image.
