An object is to provide an image processing apparatus capable of appropriately distinguishing changes in an area that have occurred over a period of time. An image processing apparatus may include: a difference image generator means to generate a difference image from input SAR images; an intensity change feature extractor means to extract an intensity-based change feature from the difference image; a speckle change feature extractor means to extract speckle-based change features from the input SAR images; a combined feature extractor means to combine the intensity change feature and the speckle change feature to generate a complete representation of changes; and a classifier means to classify the pixels in several change classes using the combined feature and output a change map.

Image processing apparatus, image processing method and non-transitory computer readable medium

An object is to provide an image processing apparatus capable of appropriately distinguishing various object types. An image processing apparatus (C) comprising: detector means () for detecting objects in an input SAR image and generating object chips; projection calculator means () for calculating projection information of each object using SAR geometry; feature learner means () for learning, for each object, a relation between an object chip and its projection information, and thereby generating learnt features of object chips; and classifier means () for classifying object chips into classes based on the learnt features of object chips.
