Fractal encoding method becomes an effective image compression method because of its
high compression ratio and short decompressing time. But one problem of known fractal …

Texture analysis refers to the branch of imaging science that is concerned with the
description of characteristic image properties by textural features. However, there is no …

Fractal image compression (FIC) is an image coding technology based on the local similarity
of image structure. It is widely used in many fields such as image retrieval, image denoising …

Head pose estimation (HPE) represents a topic central to many relevant research fields and
characterized by a wide application range. In particular, HPE performed using a singular …

Face recognition is widely considered as one of the most promising biometric techniques,
allowing high recognition rates without being too intrusive. Many approaches have been …

In this paper, a new similarity measure for fractal image compression (FIC) is introduced. In
the proposed Huber fractal image compression (HFIC), the linear Huber regression …

This study presents insights into the computational complexity of fractal image compression
(FIC) algorithms. Unlike JPEG, a fractal encoder necessitates more CPU time in contrast to …
