My work is about studying texture images using wavelets. The very idea of texture is ill-defined, but it includes the underlying concept of periodicities, which leads to think of a frequential study. And the idea of using wavelets is supported by biological studies that have shown that the human brain naturally uses multiscale processing for vision.
The adaptive wavelet packet decomposition highlights a very specific distribution (in fact, a bimodal one) for the resulting coefficients in some subbands (whose frequency support is rather narrow). Therefore, my work consists in modeling these distributions and estimating their parameters. |
