Wavelet Transform Filtering
• wave2d(M, n)—Returns the n level wavelet transform of M.
• iwave2d(M, n)—Returns the n level inverse wavelet transform of M.
• wavescale(M, n, Min, Max)—Returns the n level wavelet transform of M, scaled between Min and Max.
The functions return a matrix containing the transformed image.
Arguments
• M is an image matrix. The number of rows and columns must be divisible by 2n.
• n is a positive integer, or 0, representing the wavelet level.
• Min, Max are real numbers representing the minimum and maximum intensity scale for viewing.
