You can download the header files and sample programs for wavelet transform in OpenCV here. You should download the file wavelib.rar. The instructions to implement Wavelet Transform in OpenCV are explained in detail in Doc-wavelib.pdf.
The sample program for 2D wavelet transform demo has been provided in the manual mentioned above. The folders 'linuxshared' and 'linuxstatic' contains the shared and static library files respectively. Some sample programs which demonstrate the applications of wavelet transform are provided in the examples folder. Initially you may face some difficulties in generating the sym links of wavelet, but be patient.
