摘要： A location estimating apparatus according to an embodiment includes a degree-of-similarity calculator, a correspondence calculator, and a location calculator. The degree-of-similarity calculator calculates a degree of similarity between the input image and the reference image by an arithmetic operation that varies, in a non-discrete manner, the degree of similarity in accordance with a non-discrete variation of a first parameter. The correspondence calculator calculates correspondence between a pixel of the input image and a pixel of the reference image by an arithmetic operation that varies, in a non-discrete manner, the correspondence in accordance with a non-discrete variation of a second parameter. The location calculator calculates a first location indicating a position and/or an orientation of the first imaging device when the input image is captured by an arithmetic operation that varies, in a non-discrete manner, the first location in accordance with a non-discrete variation of the correspondence.

摘要： An object region identifying apparatus according to an embodiment identifies to which one of a plurality of predetermined object classes each pixel of an image belongs to label the pixel with an object type. The object region identifying apparatus includes following units. A base cost calculating unit calculates base costs of the respective object classes in each of the pixels. A transition cost estimating unit estimates a transition cost accrued when a transition between the object classes occurs between adjacent pixels in the image. A cumulative cost calculating unit calculates cumulative costs of the respective object classes in each of the pixels by accumulating the base cost and the transition cost for the respective object classes along a scanning direction set on the image. A class determining unit determines the object class of each of the pixels based on the corresponding cumulative cost.

摘要： According to one embodiment, an image processing device includes first storage and a processor. The first storage is configured to store a first statistical model generated by learning bokeh which occurs in a first image. The processor is configured to acquire a second image, acquire a bokeh value which indicates bokeh occurring in the second image and an uncertainty level which indicates a level of uncertainty for the bokeh value, generate a first bokeh map based on the bokeh value and uncertainty level, and acquire a second bokeh map obtained by interpolating a bokeh value with respect to the first bokeh map. The bokeh value and the uncertainty level are output from the first statistical model by inputting the second image into the first statistical model.
