Abstract
An apparatus comprising a plurality of image sensors configured to capture an image and a processor. The processor may comprise a buffer. The processor may be configured to (i) receive data from the image in a sequential order, (ii) perform cost calculations on the data, (iii) store the data in the buffer in a direction, (iv) when data corresponding to an end of a line of pixels of the image is stored, perform a second cost calculation on the stored data corresponding to the line and (v) reverse the direction of storing the data in the buffer. An order for the second cost calculations on the line of the data may be last in, first out. The data may be stored while the second cost calculations are performed. Data may not be removed from the buffer until the second cost calculation has been performed on the data.
