recent studies on wavelet transform and fractal modeling applied on mammograms for the detection of cancerous tissues indicate that microcalcifications and masses can be utilized for the study of the morphology and diagnosis of cancerous cases. it is shown that the use of fractal modeling, as applied to a given image, can clearly discern cancerous zones from noncancerous areas. in this paper, f...

The high complexity of the remotely sensed images and measurements provided by the last generations of sensors demand new techniques for scene understanding and analysis. The similarity of fractal and real world objects was observed and intensively studied from the very beginning. The fractal geometry became a tool for computer graphics and data visualisation in the simulation of the real world...

This paper presents a new approach to fractal image generation by translating the evolution of graph grammar into graphics output. It uses the algebraic approach of graph grammar as a powerful abstract modeling tool for the generation of selfsimilar fractal images via its graph production, derivations and double-pushout construction. We focus on three proposed methods for image generation which...

It generates Message Authentication Image (MAI) by using Fractals and chaos theory. The fractal images are generated by using Iterated Function System (IFS) techniques. We implemented and generated the f...

This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...

This paper presents a new approach to computer image generation via three proposed methods for translating the evolution of a Petri net into fractal image synthesis. The idea is derived from the concept of fractal iteration principles in the escape-time algorithm and chaos game. The approach uses a Petri net as a powerful abstract modeling tool for fractal image synthesis via its duality, deadl...

This work proposes the development and study of a novel technique for the generation of fractal descriptors used in texture analysis. The novel descriptors are obtained from a multiscale transform applied to the Fourier technique of fractal dimension calculus. The power spectrum of the Fourier transform of the image is plotted against the frequency in a loglog scale and a multiscale transform i...

Now a days most of the researchers are doing lots of work in the area of image compression. Fractal image compression requires lots of mathematical computation to compress an image. Fractal image compression is a recent technique based on the representation of an image by a contractive transform, on the space of images, for which the fixed point is close approximation to the original image. Mai...

nowadays, quality control of bread, especially in large scale production, requires application of novel methods. in this research, image analysis of digital images of barbary bread enriched with soy flour was carried out at two storage intervals. using imagej software, crumb features (mean cell area and void fraction) were computed for each image. fractal dimensions of bread crumb images were m...

Data security has become an important issue in recent times. Confidential data needs to be protected from unauthorized users. Various image encryption techniques have been proposed for the secure transmission of images to protect the authenticity, integrity and confidentiality of images. Fractal images can be used as a strong key for the encryption due to the random and chaotic nature of fracta...
