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.

Abstract translation: 确定偏移的方法包括：将当前图像划分为多个块，基于相邻像素的值来确定多个块中的每个块中的像素的类别，确定属于该类别的像素的偏移值，以及调整 基于类别的特性和每个像素的背景像素值的偏移值。 偏移值是原始图像的值与属于一个类别的像素的还原图像之间的差的平均值。 背景像素值是被划分的像素属于背景像素块的背景像素块中的像素的值的平均值，以计算背景像素值。

Abstract: A method of decoding an image including: obtaining information about an intra prediction mode applied to a current block to be decoded, from a bitstream; obtaining one of a left neighboring pixel whose location is determined based on j*dy>>n and a up neighboring pixel whose location is determined based on i*dx>>m, where a current pixel is located on (i,j), dx, dy, m and n are integers; performing intra prediction on the current pixel using one of the left neighboring pixel and the up neighboring pixel.
