摘要： A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.

摘要： An encoding apparatus includes an encoder for encoding an alpha-map signal for discriminating a background from an object of an input picture in motion compensation prediction (MV)+transform encoding which uses MV in a domain of each of N.times.N transform coefficients (n), a transform circuit for transforming Pf into n in accordance with the alpha-map signal, an inverse transform circuit for reconstructing Pf by inversely transforming n in accordance with the alpha-map signal, a selector for obtaining a motion compensation prediction value (p) in the mth layer (m=2 to M) by switching p in the mth layer and p in the (m-1)th layer for each n, the selector selecting p in the mth layer for n by which a quantized output (Q) in the (m-1)th layer is 0 and selecting p in the (m-1)th layer for n by which Q=1 or more, an adder for calculating a difference df between a prediction error signal in the mth layer and a dequantized output in the (m-1)th layer, and an encoder for encoding and outputting the quantized signal of df. This encoding apparatus realizes SNR scalability in M layers.

摘要： An object extraction method comprising the steps of comparing each portion of first image data obtained by capturing an extraction object with another portion of the first image data or second image data, thereby generating shape data as an image representing a provisional region of the extraction object in the first image data, and matching a contour of the shape data to a contour of the extraction object by using the first image data and the provisionally generated shape data.

摘要： A video phone unit comprising a decoder for expanding a received picture transmitted from the other party, a television camera for photographing a subject for producing a photographed picture on one party side, a hook for detecting whether the camera is immobile or mobile and generating either a first detecting signal indicating that the hook is in a mobile state or a second detecting signal indicating that the hook is immobile, a changeover switch for selecting either the received picture expanded at the decoder or the photographed picture taken at the camera after receiving the first or second detecting signal provided from the hook, a display for displaying one picture selected at the changeover switch, and a coder for compressing and transmitting the photographed picture provided from the camera to the other party.
