A probability function with highest likelihood is calculated based on data. A canonical distribution in statistical physics and a temperature parameter of the canonical distribution are calculated as a fluctuation of the data. A probability function is estimated using the calculated probability function with the highest likelihood, the calculated fluctuation, and the canonical distribution. The present technology is applicable to an apparatus that estimates and uses a probability function.

An image processing apparatus includes a dividing unit, a first extracting unit, a quantizing unit, a generating unit and an image output unit. The dividing unit divides an object image into regions. The first extracting unit extracts image features of the regions generated by the dividing unit. The quantizing unit quantizes the image features extracted by the first extracting unit. The generating unit generates an expected value of an occurrence probability of each topic variable indicating similar images from the image features quantized by the quantizing unit, using a correlation between the image features quantized by the quantizing unit and the topic variables. The image output unit outputs an image of a defective portion in the object image, using the expected values of the occurrence probabilities of the topic variables generated by the generating unit.

An image analyzer for detecting a target object from image data, includes a reference detection unit, a primary detection unit, a secondary detection unit and an output unit. The reference detection unit detects a reference object included in the image data. The primary detection unit detects candidates for the target object from the image data. The secondary detection unit specifies a portion including the target object from among the candidates, by using a correlation between a feature of the detected reference object and a feature of the candidates. The output unit outputs information representing the portion including the target object specified by the secondary detection unit.
