Image clustering method

IMAGE CLUSTERING METHOD Disclosed is a method of determining one or more event subsets within a plurality of 5 images. Each image is associated with time and location data specifying the time and location of capture of the image by an image capture device. The method determines (611) a time variable for each adjacent pair of images in a capture time ordered list (605) of the plurality of images based on the time data associated with the images of the pair. A distance variable for each adjacent pair of images in the ordered list of images is then 10 determined (615) based on the location data associated with the images of the pair. The method determines (621) speed data of the image capture device at the time and location of capture of each image in the plurality of images. The ordered list of images is then partitioned (641) into one or more event subsets on the basis of a cost function (631), the cost function being determined in accordance with a normalisation (625) of the time 15 variable and distance variable, wherein the time variable and the distance variable are weighted relative to the speed data. 4936080_1 991840_specijlodge Sort photos Determine time variable 611 between photo pairs Determine distance variable 615 between photo pairs Determine speed 621 variable between photos Normalise time and 625 distance variable Calculate cost between 631 all pairs of photos Identify peaks in the cost 635 function Create Events End Fig. 6
