Featureless global alignment of multiple images
The majority of the approaches to the automatic recovery of a panoramic image from a set of partial views are suboptimal in the sense that the input images are aligned, or registe...

Gray-scale image enhancement using the SMQT
This paper explores the Successive Mean Quantization Transform (SMQT) for automatic enhancement of gray-scale images. The transform is in the paper presented using set theory. The...

Analyzing symmetry in biological systems
This paper suggests a new measure of symmetry for bifurcating structures, which relies not only on topology and ordering, but also on quantitative properties (e.g. length of branc...

Lossy to lossless image compression using allpass filters
In this paper, an effective implementation of the allpass-based orthonormal symmetric wavelets is proposed for image compression. Since the orthonormal symmetric wavelets are used...

Discrete bandelets with geometric orthogonal filters
This paper describes the construction of second generation bandelet orthogonal bases. The decomposition on a bandelet basis is computed using a wavelet filter bank followed by ada...

Homogeneity-based directional sigma filtering of video noise
This paper proposes a real-time method for the reduction of white Gaussian video noise. The method achieves a maximum gain of 4.8 dB and is capable of preserving image content. It...

Mosaic-based 3D scene representation and rendering
- In this paper we address the problem of fusing images from many video cameras or a moving video camera. The captured images have obvious motion parallax, but they will be aligned...

Multiple active contour models based on the EM algorithm
This paper describes an algorithm for the extraction of multiple regions using multiple active contour models (ACMs). The algorithm organizes edge points into strokes and assigns ...

Direct image retrieval in JPEG and JPEG2000
Images are often compressed using JPEG or JPEG2000. Many retrieval systems operated in either uncompressed or compressed domains have been proposed. However, retrieving in multipl...
