Abstract: A method of processing image data, the image data comprising a plurality of data values arranged in two or more sequences, each sequence comprising a first number of data positions each having a data value of the plurality, and each data value comprising a second number of bits, the method comprising: upon receiving each sequence of the two or more sequences, processing the data values of the sequence to determine, for each given data position of the first number of data positions, a representative value for the given data position based on a relationship between the data value at the given data position and the data value at one or more neighbouring data positions.

Abstract: Methods and systems for reducing the appearance of block-related artifacts are described. The methods include obtaining image frames in a sequence of image frames and adjusting some or all image frames in the sequence of image frames to generate adjusted image frames. The adjusted image frames may be created by generating image data and adding it to one or more edges of the image frame or by discarding image data from the image frame. The adjusted image frames shift a block origin relative to image data in the image frame. The adjusting is performed so that the shift of the block origin varies during the sequence of image frames. A block-based process is applied to each adjusted image frame to generate processed image frames, wherein blocks of image data are selected and processed in each adjusted frame of image data according to the block origin.

Abstract: A method of data processing in a data processing system comprising a computer vision system. The method comprises obtaining image data representative of a plurality of pixels of an image, the image data comprising a plurality of pixel intensity values respectively representing said pixels. The method comprises identifying one or more compromised pixel intensity values in the plurality of pixel intensity values. The method comprises generating sensor defect state data relating to the identified compromised pixel intensity values. The method comprises performing, using the computer vision system, a feature recognition process on the image data. The method comprises performing an action based on the sensor defect state data.
