Patent ID: 8813111

Claim:
A method for playing a photograph-based game comprising: establishing a communication link between a game playing system and at least one game playing device which is operated by a player; providing for presenting of game rules to the player on the at least one game playing device, the game rules including a plurality of tasks for the submission of at least one photographic image that is relevant to a category, the tasks being presented sequentially; for each of the tasks: providing for receiving a photographic image in the game playing system submitted via the established link from the game playing device; computing an image signature for the submitted photographic image, the image signature comprising a multidimensional vector or graph which is a statistical representation of visual features extracted from patches of the photographic image; and computing a relevance to the task, based on the computed image signature, the computing of the relevance to the task comprising classifying the image signature with a pretrained classifier model that has been trained on a training set of image signatures and respective labels, the training set of image signatures including image signatures computed for images that are labeled as relevant to the category; and presenting a score to the player based on the computed relevance for the task before presenting a next of the tasks.
