    Abstract: A method of predictive-decoding a multi-view image includes receiving a bitstream comprising information indicating whether each of pictures included in multi-view image sequences is a reference picture referred to by others of the pictures included in the multi-view image sequences for inter-view prediction and data about the multi-view image sequences; extracting the information indicating whether each of pictures included in multi-view image sequences is the reference picture and the data about the multi-view image sequences from the received bitstream; determining whether pictures included in the data about the multi-view image sequences are to be used for inter-view prediction decoding based on the extracted information indicating whether each of pictures included in multi-view image sequences is the reference picture; and performing predictive-encoding based on a result of the determination, wherein the information indicating whether each of pictures included in multi-view image sequences is the reference picture is included in a parameter for each of the pictures.

    Abstract: A method of determining an offset includes dividing a current image into a plurality of blocks, determining a category of pixels in each of the plurality of blocks based on values of neighboring pixels, determining an offset value for pixels belonging to the category, and adjusting the offset value based on characteristics of the category and a background pixel value of each of the pixels. The offset value is an average of differences between values of original images and restored images of pixels belonging to one category. The background pixel value is an average of values of pixels in a background pixel block to which the pixels belong among background pixel blocks divided to calculate a background pixel value.
