    摘要: The disclosure relates to a method comprising receiving an image;filtering the image by a first filter to obtain a set of first filtered values and by a second filter to obtain a set of second filtered values. The first filtered values are stored. An algorithm is applied to the set of first filtered values and the set of second filtered values to obtain a set of results. At least one local maximum, local minimum or both of the results are searched to determine a location of an interest point. A descriptor is determined for a detected interest point on the basis of the stored one or more first filtered values. The disclosure also relates to an apparatus and a storage medium.

    摘要: Various methods are described for improving the compression of location information during a visual search. One example method may comprise identifying one or more features of a source query image for a visual search. The method may further comprise generating a histogram map comprising one or more histogram bins, wherein the histogram map represents the location of the one or more features of the source query image. Additionally, the method may comprise generating a context for at least one of the one or more histogram bins, wherein the context comprises a first context value based on information related to one or more neighboring bins located a first distance from the respective histogram bin and a second context value based on information related to one or more neighboring bins located a second distance from the respective histogram bin. Similar and related methods, apparatuses, and computer program products are also provided.
