The representation and modelling of regions is an important topic in computer vision. In this paper, we represent a region via a level set of a 'phase field' function. The function is not constrained, e.g. to be a distance function; nevertheless, pha... Read More about Phase field models and higher-order active contours.

Texture-adaptive mother wavelet selection for texture analysis (2005)
Conference Proceeding
Abhayaratne, G., Jermyn, I., & Zerubia, J. (2005). Texture-adaptive mother wavelet selection for texture analysis. In 2005 International Conference on Image Processing (ICIP) : September 11-14, 2005, Genova, Italy (1290-1293). https://doi.org/10.1109/icip.2005.1530299

Classification results obtained using wavelet-based texture analysis techniques vary with the choice of mother wavelet used in the methodology. We discuss the use of mother wavelet filters as parameters in a probabilistic approach to texture analysis... Read More about Texture-adaptive mother wavelet selection for texture analysis.

New higher-order active contour energies for network extraction (2005)
Conference Proceeding
Rochery, M., Jermyn, I., & Zerubia, J. (2005). New higher-order active contour energies for network extraction. In 2005 International Conference on Image Processing (ICIP) : September 11-14, 2005, Genova, Italy (822-825). https://doi.org/10.1109/icip.2005.1530182

Using the framework of higher-order active contours, we present a new quadratic continuation energy for the extraction of line networks (e.g. road, hydrographic, vascular) in the presence of occlusions. Occlusions create gaps in the data that frequen... Read More about New higher-order active contour energies for network extraction.

Multimodal statistics of adaptive wavelet packet coefficients: experimental evidence and theory (2005)
Conference Proceeding
Cossu, R., Jermyn, I., & Zerubia, J. (2005). Multimodal statistics of adaptive wavelet packet coefficients: experimental evidence and theory. In PSIP'2005 : fourth international conference on physics in signal and image processing, Toulouse, France, 31 January-2 February 2005 ; proceedings

In recent work, it was noted that although the subband histograms for standard wavelet coefcients take on a generalized Gaussian form, this is no longer true for wavelet packet bases adapted to a given texture. Instead, three types of subband statist... Read More about Multimodal statistics of adaptive wavelet packet coefficients: experimental evidence and theory.
