Abstract: The present invention provides an image processing apparatus including a skeleton component separation unit configured to separate a skeleton component illustrating a perspective structure from a source image, a mist/fog correction unit configured to calculate, based on color information in each color channel of the skeleton component, a correction factor that lowers brightness of a pixel as the pixel is brighter and correct, based on the correction factor, brightness of each pixel of the source image, and a brightness restoration unit configured to restore brightness of the brightness-corrected source image to brightness of environmental light as target brightness.

Abstract: 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.

Abstract: The invention enables image processing of visible light and near-infrared light using an imaging device. An acquisition unit (110) acquires an image signal representing an image including near-infrared light that has an intensity according to a pattern having a prescribed geometric shape. A signal processing unit (120) uses pattern information which defines the pattern to output, a color signal representing visible light components corresponding to the image signal and a near-infrared signal representing near-infrared light components corresponding to the image signal.

Abstract: In order to properly detect an outbreak of smoke using a photographic image, this detection device is equipped with an extraction unit, a calculation unit, and a detection unit. By using an image analysis result of an input image, that is, a photographic image captured of a scene under surveillance, the extraction unit generates an image for which a noise component is removed from the input image. By using brightness information contained in the generated image, the calculation unit calculates an attenuation factor of reflected light from a captured object in the input image. The detection unit determines whether an outbreak of smoke is present in the scene under surveillance based on the attenuation factor.
