A projection apparatus includes a prism holder for holding a synthesizing prism, the prism holder including a first positioning portion and being positioned and fixed to one end plane and the other end plane of the synthesizing prism opposite to each other, except for incidence planes of the synthesizing prism on which respective color light beams are incident and an outgoing plane of the synthesizing prism for outputting a synthesized light flux to the side of a projection optical unit, and a lens holder for holding the prism holder and a projection lens, the lens holder including a second positioning portion which is fitted to the first positioning portion of the prism holder to make positioning and fixing. Thus, assembling can be made with accuracy and without fail while positioning is made to the optical modulation element, the synthesizing prism, and the projection lens.

The optical illumination system of a liquid crystal panel (18) includes an integrator having a first lens array (21) made up of a plurality of lens elements and a second lens array (22) made up of lens element corresponding to the lens elements of the first lens array (21). A single ray bundle incident on the first lens array (21) is split into a plurality of split ray bundles by the first lens array (21) and pass through the corresponding lens elements of the second lens array (22) and further through a collimator lens (15), dichroic mirrors (16B, 16R, 16G) and enter the liquid crystal panel (18). The liquid crystal panel (18) is illuminated with the ray bundles sent from all the lens elements of the first lens array (21) in a superimposing manner and the illuminance distribution is made even. The projection-type liquid crystal display apparatus is provided for preventing a reduction in image quality due to deposited foreign substances such as dust, arc fluctuations of a light source and so on.

摘要:
Systems and methods for implementing a superpixel boosted top-down image recognition framework are provided. The framework utilizes superpixels comprising contiguous pixel regions sharing similar characteristics. Feature extraction methods described herein provide non-redundant image feature vectors for classification model building. The provided framework differentiates a digitized image into a plurality of superpixels. The digitized image is characterized through image feature extraction methods based on the plurality of superpixels. Image classification models are generated from the extracted image features and ground truth labels and may then be used to classify other digitized images.
