摘要： An image encoding apparatus includes a converter 1 for receiving an image signal, and for converting the image signal of individual blocks to DC components and AC components by orthogonal transformation of the individual blocks of an image frame; a predicted reference value generator 2 for receiving the image signal, and for generating a predicted reference value of each image frame from DC components resulting from the orthogonal transformation of left-edge blocks of the image frame; and a differential unit 3 for obtaining difference values between the DC components output from the converter 1 and the predicted reference value generated by the predicted reference value generator 2. The image encoding apparatus outputs a bit stream by quantizing and variable-length encoding the AC components and difference values obtained by the differential unit 3, and by quantizing and variable-length encoding the predicted reference value to be added to a header.

摘要： An image discrimination apparatus includes an inter-frame distance calculating unit 2 for calculating an inter-frame distance which is a distance between features from the feature of a current frame extracted by a feature extracting unit 1 and the feature of an immediately-preceding frame stored in a feature buffer 3, and a cut-point-determination data calculating unit 4 for calculating statistics values of inter-frame distances and calculating a threshold for determination of cut points from the statistics values. The image discrimination apparatus compares the inter-frame distance of the current frame with the threshold for determination of cut points to determine a cut point from the comparison result.
