Technologies are generally described for performing image analysis of an image using a repeating geometric sequence. In some examples, a computing system accesses image data that defines an image for image analysis. The computing system determines a repeating geometric sequence that generates variously oriented edges or sub-regions in the image data. The computing system applies the repeating geometric sequence to the image data, thereby generating a series of coordinates that represent the image data defined by the variously oriented edges or sub-regions. The coordinates are determined by the variously oriented edges or sub-regions and not by horizontal or vertical Cartesian lines. The computing system organizes the image data represented by the series of coordinates into a set of one or more arrays and performs image analysis on the set of one or more arrays to produce an image analysis result for the image data.
