    Re: What is the difference between Gabor filter and a gabor wavelet?

    Usually 2D design of Gabor filters require DESIGN in 2D Frequency ( because it can easily get out of boounds!). This is related to several issues:
    a) not obeying the Nyquist criteria
    b) phase distortions
    c) not forming a '' frame''
    d) mack up in 2D frequencies
    and some others. The design in space is naive.

    Re: What is the difference between Gabor filter and a gabor wavelet?

    Firstly, thanks for replying. Just to clarify(if wrong do correct me), a Gabor filter is made up of Gabor wavelets. Am i right to say this? or what is the relationship between gabor filters and Gabor wavelets?
