Abstract: Encoding input data includes: generating a first block of coefficients based on a transform performed on a residual block of data for multiple pixels; generating reference information based on a reference block of data corresponding to the residual block of data; and determining losslessly decodable code values representing the first block of coefficients based on the reference information.

Abstract translation: 编码输入数据包括：基于对多个像素的剩余数据块执行的变换来生成第一系数块; 基于与所述剩余数据块相对应的数据的参考块生成参考信息; 以及基于所述参考信息确定表示所述第一系数块的无损解码代码值。
