WebIf it is a vector, you can use pywavelets (forward DWT, truncation, backward DWT). If it is an expression, you may want to sample it and use pywavelets. This will give you an idea of how well the approximation will be. You can also implement the expansion into the (truncated) Haar basis by yourself using numerical or symbolic integration. WebThe 2D dual-tree wavelet transform produces six subbands at each scale, each of which are strongly oriented at distinct angles. In addition to being spatially oriented, the 3D dual-tree wavelet transform is also motion selective - each subband is associated with motion in a specific direction. daphne on the company you keep birthing in our community
