Provide is an image decoding apparatus which reliably prevents deterioration of the image quality of decoded images which have been previously coded. An image decoding apparatus (200) includes: an inverse quantization and inverse orthogonal transform unit (220) and an adder (230) which decode a coded image included in a coded stream (Str) to generate a decoded image (Rc); an entropy decoding unit (210) which extracts cross-correlation data (p) which indicates a cross-correlation between the decoded image (Rc) and an image which corresponds to the decoded image and has not yet been coded; and an adaptive filter (240) which computes a filter parameter (w) based on the extracted cross-correlation data (p), and performs a filtering operation on the decoded image (Rc) according to the filter parameter (w).
An image coding apparatus which codes an input image, said image coding apparatus comprising:
An image coding method for coding an input image, said image coding method comprising:
A non-transitory computer-readable medium having a program stored thereon for coding an input image, said program causing a computer to execute:
An integrated circuit which codes an input image, said integrated circuit comprising:
