摘要： A first arithmetic apparatus performs an arithmetic process, out of a plurality of arithmetic processes in identification processing on an input image, in which the parameter amount that is used is small compared to an amount of data to which the parameters are applied. A second arithmetic apparatus performs an arithmetic process, out of the plurality of arithmetic processes, in which the parameter amount that is used is large compared to an amount of data to which the parameters are applied. The second arithmetic apparatus can use a larger memory capacity memory than the first arithmetic apparatus.

摘要： An image processing method is provided for an image processing apparatus which executes processing by allocating a plurality of weak discriminators to form a tree structure having branches corresponding to types of objects so as to detect objects included in image data. Each weak discriminator calculates a feature amount to be used in a calculation of an evaluation value of the image data, and discriminates whether or not the object is included in the image data by using the evaluation value. The weak discriminator allocated to a branch point in the tree structure further selects a branch destination using at least some of the feature amounts calculated by weak discriminators included in each branch destination.

摘要： An information processing apparatus comprises a processing unit configured to execute, in frame periods corresponding to respective frames, an inference relating to the frame and training relating to the frame. When an inference relating to a first frame has been completed but training relating to the first frame has not been completed in a first frame period corresponding to the first frame, the processing unit executes training relating to the first frame and an inference and training relating to a second frame in a second frame period corresponding to the second frame subsequent to the first frame.

摘要： There is provided with a processing apparatus. A data holder holds at least some of data of a plurality of channels in a target layer among a plurality of layers. Each of a plurality of processors performs, in parallel, a product-sum operation using the data of one channel of the target layer and a coefficient corresponding to the target layer. A selector selects whether to perform first processing or second processing on the basis of information specifying processing in the target layer. The first processing includes inputting the data of one channel of the target layer into one of the plurality of processors. The second processing includes inputting the data of one channel of the target layer to the plurality of processors in parallel.
