Method and apparatus for image coding and/or decoding using a position and shape map

   
   

A method or apparatus for decoding an image data comprising decoding a coded map signal indicative of a position and shade of a content in a screen inputted for every block of picture signals; decoding coded orthogonal transform coefficients and an average value of pixels inside of the content; performing a two-dimensional inverse orthogonal transform of an orthogonal transform coefficient; and deriving a regenerative picture signal by synthesizing results of the two-dimensional inverse orthogonal transform, with the average value.

Um método ou um instrumento para descodificar uns dados da imagem que compreendem descodificando um sinal codificado do mapa indicativo de uma posição e de uma máscara de um índice em uma tela inputted para cada bloco do retrato sinalizam; orthogonal codificados descodificar transformam coeficientes e um valor médio dos pixels dentro do índice; executando um orthogonal inverso bidimensional transforma de um orthogonal transforma o coeficiente; e derivando um sinal regenerative do retrato por resultados synthesizing do orthogonal inverso bidimensional transforme, com o valor médio.
