Gap Closure in (Road) Networks Using Higher-Order Active Contours (2004)
Presentation / Conference Contribution
Rochery, M., Jermyn, I., & Zerubia, J. (2004, October). Gap Closure in (Road) Networks Using Higher-Order Active Contours. Presented at IEEE International Conference on Image Processing (ICIP), Singapore

We present a new model for the extraction of networks from images in the presence of occlusions. Such occlusions cause gaps in the extracted network that need to he closed. Using higher-order active contours, which allow the incorporation of sophisti... Read More about Gap Closure in (Road) Networks Using Higher-Order Active Contours.

Texture Analysis Using Adaptive Biorthogonal Wavelet Packets (2004)
Presentation / Conference Contribution
Abhayaratne, G., Jermyn, I., & Zentbia, J. (2004, October). Texture Analysis Using Adaptive Biorthogonal Wavelet Packets. Presented at 2004 IEEE International Conference on Image Processing (ICIP), Singapore

We discuss the use of adaptive biorthogonal wavelet packet bases in a probabilistic approach to texture analysis, thus combining the advantages of biorthogonal wavelets (FIR, linear phase) with those of a coherent texture model. The computation of th... Read More about Texture Analysis Using Adaptive Biorthogonal Wavelet Packets.

Texture Discrimination Using Multimodal Wavelet Packet Subbands (2004)
Presentation / Conference Contribution
Cossu, R., Jermyn, I., & Zerubia, J. (2004, October). Texture Discrimination Using Multimodal Wavelet Packet Subbands. Presented at 2004 IEEE International Conference on Image Processing (ICIP), Singapore

The subband histograms of wavelet packet bases adapted to individual texture classes often fail to display the leptokurtotic behaviour shown by the standard wavelet coefficients of 1natural' images. While many subband histograms remain leptokurtotic... Read More about Texture Discrimination Using Multimodal Wavelet Packet Subbands.

Texture Analysis Using Probabilistic Models of the Unimodal and Multimodal Statistics of Adaptive Wavelet Packet Coefficients (2004)
Presentation / Conference Contribution
Cossu, R., Jermyn, I., & Zerubia, J. (2004, May). Texture Analysis Using Probabilistic Models of the Unimodal and Multimodal Statistics of Adaptive Wavelet Packet Coefficients. Presented at 2004 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), Montreal, Canada

Although subband histograms of the wavelet coefficients of natural images possess a characteristic leptokurtotic form, this is no longer true for wavelet packet bases adapted to a given texture. Instead, three types of subband statistics are observed...
