  • Patent number: 8472721
    Abstract: A pattern identification unit generation method of generating a pattern identification unit in which a weak discriminator array obtained by cascade-connecting a plurality of weak discriminators branches, and weak discriminator arrays are connected to respective arms after branching, evaluates based on a processing result obtained by inputting a set of evaluation data to the weak discriminator array whether or not a weak discriminator array after branching reaches the number of stages to be connected. The number of stages of weak discriminators to be connected without branching as the weak discriminator array is determined based on this evaluation result.

  • Patent number: 8401313
    Abstract: 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.

  • Patent number: 8268020
    Abstract: A battery case is formed by drawing a metallic plate thin to form a cylindrical body 10 having a closed end and cutting away part of the cylindrical body 10 at an opening 11 thereof in the direction perpendicular to an axis of the cylindrical body 10. The cutting of the cylindrical body 10 is carried out by moving a second blade 30 arranged outside the cylindrical body 10 relatively toward the axis of the cylindrical body with a first blade kept abutting the inner circumference of the cylindrical body 10. As a result, an inward burr 13 extending in the direction perpendicular to the side face of the cylindrical body 10 is formed on a cut surface 12 of the cylindrical body 10, but the burr 13 is prevented from entering the battery case.
