1. An image processing equipment for performing kernel discriminant analysis based on a photographed image of an object comprising: an input feature vector generation unit for generating, based on data related to said image, an input feature vector including as elements a size of said object, a side portion shape of said object, and an upper portion shape of said object; a discriminant analysis operations unit for generating a vector mapped to a discriminant space, through performing the operations for kernel discriminant analysis based on said input feature vector; and an object determination unit for determining whether said object is a pedestrian or not, according to whether or not the vector mapped to said discriminant space exists within a fixed area at the discriminant space.
