The aim of the work presented in this paper is to discriminate natural images (NI) and
computer generated graphics (CG). The texture differences are analyzed to the residual …

Fractal theory provides a powerful mathematical tool for texture segmentation. However, in
spite of their increasing popularity, traditional fractal features are intrinsically of less …

The Hurst parameter for two-dimensional (2-D) fractional Brownian motion (fBm) provides a
single number that completely characterizes isotropic textured surfaces whose roughness is …

To discriminate the acquisition pipelines of digital images, a novel scheme for the
identification of natural images and computer‐generated graphics is proposed based on …

The separation of coal and gangue is an important process of the coal preparation
technology. The conventional way of manual selection and separation of gangue from the …

Rendering technology in computer graphics (CG) is now capable of producing highly
photorealistic images, giving rise to the problem of how to identify CG images from natural …

Based on the gliding-box and relative differential box-counting algorithms, a novel method
that estimates accurately the multifractal exponents, a distinct characteristics of gray-scale …

Texture recognition is one of the most important tasks in computer vision, with numerous
applications in several areas. Despite the recent success of end-to-end deep learning …

Multifractal theory has been widely used in different kinds of fields. In this paper, methods
were proposed to extract two kinds of multifractal descriptors of gray series and two …

Computer graphics identification has gained importance in digital era as it relates to image
