In this paper, we propose an original approach in order to improve the results of color image
segmentation by pixel classification. We define a new kind of color space by selecting a set …

Forest fires are a common feature in the Mediterranean forests through the years, as a wide
tract of forest fortune is lost because of the incendiary fires in the forests. The enormous …

We propose a new method for image reconstruction based on circulant matrices. The
novelty of this method is the image treatment using a simple and classical algebraic …

Most coding techniques for color image compression employ a de-correlation approach—
the RGB primaries are transformed into a de-correlated color space, such as YUV or YCbCr …

Although subband transform coding is a useful approach to image compression and
communication, the performance of this method has not been analyzed so far for color …

Face recognition systems based on'conventional'images have reached a significant level of
maturity with some practical successes. However, their performance may degrade under …

Let R and S be m× m and n× n nontrivial real symmetric involutions. An m× n complex matrix
A is termed (R, S)-conjugate if A¯= RAS, where A¯ denotes the conjugate of A. In this paper …

In this paper, signal flow graphs are mainly addressed for the efficient and forward stable
Discrete Sine Transform (DST) algorithms having sparse, scaled orthogonal, rotational …

We propose a color-image segmentation algorithm by unsupervised classification of pixels.
The originality of the proposed approach consists in iteratively identifying pixel classes by …

In this article, we offer an original study on the analysis of the texture of colour images based
on Local Linear Transforms (LLT). Our colour approach is based on the separability of the …
