In an embodiment of the invention a digital image is segmented to define one or more image segments, each image segment being part of an image having similar visual characteristics. Next, segmentation data comprising a set of values or ranges of values of parameters representing properties of the image segments are generated. The segmentation may be used to reconstruct the image thereby providing a means to compress the image. The segmentation data may also be used for the purposes of searching, sorting, indexing or categorising the image. The segmentation data is analysed and compared with a mapping between one or more sets of segmentation data and one or more keywords. The keywords mapped onto the analysed segmentation data are then associated with the image. The presence of objects within the image may be determined by analysing the segmentation data of a subset of the image segments and comparing the analysed segmentation data with a mapping between one or more sets of segmentation data and one or more objects. |
