I see that there's very few code examples for wavelet in java, especially if you're using openCV. I had to use wavelet in java with openCV and I used the C code from @la luvia and converted to java. There was a lot of trouble while translating the code, because it had a lot of diferences in the openCV methods and ways of using it.

even if you use integer wavelets (by lifting), the same happen, and in 2D you may need $1$ more bit for each level; some detail coefficients will be negative, so uint8 will destroy the signs in a way you cannot recover afterward. So, the inverse wavelet tranform is likely to be crappy. THe simplest way around:

Nov 09, 2020 · Wavelets take both time and frequency into the consideration. This transform is apt for non-stationary signals. We know that edges are one of the important parts of the image, while applying the traditional filters it’s been noticed that noise gets removed but image gets blurry.
Jun 10, 2019 · Hough transform can detect lines, circles and other structures if their parametric equation is known. It can give robust detection under noise and partial occlusion • It can give robust detection under noise and partial occlusion. Haugh Transform Algorithm

Wavelet transform is suited for the local problem of imaging when wavelet of vanishing moments are employed (Rashid-Farrokhi et al., 1997). 1 This is due to the fact that the Hilbert transform of a function (see Section 12.1) decays rapidly if it has a large number of vanishing moments. Therefore, selecting wavelets with vanishing moments ...

The difference with the Fourier transform is that we express the signal as a sum of sine and cosine terms, while the wavelet is represented by a single wave (wavelet function). Just as in the STFT, we split the signal in the time domain and then apply the wavelet function to each segment.

resampling wavelet transform. Secondly, this method is compared with other fusion ones such as wavelet transform with nearest neighbor resampling, IHS transform and Brovery transform according to the image evaluation index. In all, it can be concluded that the bilinear resampling wavelet transform fusion is of the best fusion result.
