  • 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: 8385649
    Abstract: Learning is sequentially executed with respect to weak discriminators based on learning data held in a storage device. Upon learning, an evaluation value for the weak discriminator is calculated. It is discriminated, based on a shift of the evaluation value, whether or not the learning is overlearning. If it is discriminated that the learning is overlearning, new learning data is added. Thus, the overlearning is easily detected and the learning is efficiently executed.

  • Patent number: 8320696
    Abstract: In order to reduce wasteful operation processes by operation units, a data supply unit reads out a plurality of pieces of pixel data from an image memory and temporarily stores the pixel data in registers, and outputs the pixel data while shifting the pixel data in one direction; product-sum operators concurrently perform operation processes based on multiple pieces of pixel data outputted from the data supply unit and filter coefficients in a filter kernel. At this time, a selector within the data supply unit selects the pixel data stored in each register in accordance with the type of the filter operation process, and outputs the selected pixel data to the product-sum operators.

  • Publication number: 20120188662
    Abstract: In a vehicle door mirror device, a base is attached to a door and covered with a base cover. A gasket is disposed on a door panel of the base cover, a seal portion of the gasket seals a gap between a lower side end of the base cover and the door panel. The seal portion is extended from the gasket toward the base cover side. Therefore, even if a dimension of the gap between the lower side end of the base cover and the door panel varies, the lower side end of the seal portion can be suppressed from being separated from an outer periphery of the base cover toward the inner side, the base cover can be suppressed from looking floating from the door panel, and appearance of the gap between the lower side end of the base cover and the door panel can be improved.

  • Publication number: 20120119053
    Abstract: Accuracy of positioning of a turning body to a mounting member when the mounting member and a support member are separate components is improved. In a vehicle door mirror device, a stand of a housing device is mounted to a base by being fastened with mounting screws. Axial directions of the mounting screws are angled with respect to an axial direction of the stand. An inner periphery abutting face and a vertical abutting face of the stand are abutted against an outer periphery abutting face and a perpendicular abutting face of the base in directions perpendicular to the axis of the stand. Thus, the stand is positioned to the base in whole directions perpendicular to the axis of the stand. Therefore, positioning accuracy of the housing device and a main body portion to the base in whole directions perpendicular to the axis of the stand can be improved.
