摘要： An apparatus and method for estimating the number of objects in an input image are disclosed. The apparatus includes: a learning unit that calculates counted values of a linear regression function by learning an arbitrary image; a separation unit that separates a foreground region and a background region of the input image; an extraction unit that searches for features that require an amount of calculation that is below a particular threshold from features having high correlation with each other feature and extracts the features from the separated foreground region; and an estimation unit that estimates the number of objects in the foreground region as a dependent variable by allocating the counted values of the linear regression function that are calculated by the learning unit and the features that are extracted by the extraction unit as independent variables of a linear regression function.

摘要： Provided are apparatuses and methods for separating an image into a foreground and a background. The apparatus includes: an edge image generating unit which generates an edge image for an original image, wherein the original image includes the background and the foreground; a background edge model renewing unit which renews a background edge model based on the generated edge image; and a foreground edge extracting unit which generates a foreground edge image based on the generated edge image and the renewed background edge model.
