1. An apparatus for generating computed results based on sensor readings, the apparatus comprising: a sensor element array comprising a plurality of sensor elements, the plurality of sensor elements arranged along at least a first dimension and a second dimension of the sensor element array, each of the plurality of sensor elements capable of generating a sensor reading based on light incident upon the sensor element; a memory; at least one computation structure configured to generate a computer vision (CV) label for a subject sensor element from the plurality of sensor elements, by, when generating the CV label for the subject sensor element, only performing comparisons of the sensor reading for the subject sensor element with the sensor reading of each of a subset of a plurality of neighboring sensor elements to the subject sensor element, the plurality of neighboring sensor elements being adjacent to the subject sensor element, and retrieving from the memory previously performed comparisons of the sensor reading for the subject sensor element with the sensor reading of each of remaining neighboring sensor elements to the subject sensor element, wherein the previously performed comparisons were performed when generating the CV label for sensor elements other than the subject sensor element and wherein the comparisons from the subset of the plurality of neighboring sensor elements and the comparisons from the remaining neighboring sensor elements are together required for generating the CV label for the subject sensor element and wherein the subset is smaller than the plurality of neighboring sensor elements.
