摘要： The present disclosure relates to an apparatus and a method for information processing enabling alignment between imaged images to be more accurately performed.
With respect to a detection result of a correspondence point between an imaged image including a pattern irradiated for alignment with other imaged image, and the other imaged image including the pattern, an evaluation value with which an occurrence rate of an error in the alignment when the imaged image and the other imaged image are composed with each other is evaluated is calculated; and an irradiated position of the pattern is updated on the basis of the evaluation value calculated. The present disclosure, for example, can be applied to an information processing apparatus, an irradiation device, an imaging apparatus, an irradiation imaging apparatus, a controller, an imaging system or the like.

摘要： The present technique relates to an image processing apparatus and an image processing method that can improve the S/N and the compression efficiency. A filtering process is applied to a first image obtained by adding a residual of prediction encoding and a predicted image to generate a second image used for prediction of the predicted image. In the filtering process, pixels as a prediction tap used for prediction computation for obtaining a pixel value of a corresponding pixel of the second image corresponding to a pixel to be processed of the first image are selected from the first image. The pixel to be processed is classified into one of a plurality of classes. Tap coefficients of the class of the pixel to be processed among tap coefficients used for the prediction computation in each of the plurality of classes obtained by learning and the prediction tap of the pixel to be processed are used to perform the prediction computation to obtain the pixel value of the corresponding pixel. The present technique can be applied to, for example, an encoding apparatus or a decoding apparatus of an image.
