摘要： The present invention relates to a context modeling method and wavelet coding apparatus for a directional filtering-based wavelet transform, and a recording medium for the context modeling method. The wavelet coding apparatus of the present invention includes a discrete wavelet transform unit (110) for performing standard discrete wavelet coding or directional filtering-based discrete wavelet coding on an input image signal. Memory (130) stores information about coded signs of transform coefficients and information about a filtering direction. A context selection unit (150) selects a context from the transform coefficient sign information and the filtering direction information. An arithmetic coding unit (170) predicts a probability of occurrence of a sign desired to be coded on a basis of information about the selected context, and performs arithmetic coding on a sign of a transform coefficient received from the discrete wavelet transform unit, thus generating a bit stream.
