An example method can include the operation of computing locally normalized edge magnitudes and edge orientations for the image using a processor to form a normalized gradient image. The normalized gradient image can be divided into a plurality of image orientation maps having edge orientations. Orientation dependent filtering can be applied to the image orientation maps to form response images. A further operation can be summing the response images to obtain an aggregated filter response image. Maxima can be identified in spatial position and scale in the aggregated filter response image. Maxima in the aggregated filter response image can be defined as interest points."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting an interest point in an image using edges","description":"Technology is described for detecting an interest point in an image using edges.
