Malware Analysis Using Visualized Image Matrices
This paper proposes a novel malware visual analysis method that contains not only a visualization method to convert binary files into images, but also a similarity calculation method between these images. The proposed method generates RGB-colored pixels on image matrices using the opcode sequences extracted from malware samples and calculates the similarities for the image matrices. Particularl...
متن کاملWavelet Analysis for Image Processing
Wavelet transforms have become increasingly important in image compression since wavelets allow both time and frequency analysis simultaneously. This paper investigates the fundamental concept behind the wavelet transform and provides an overview of some improved algorithms on the wavelet transform. The latter part of this paper emphasize on lifting scheme which is an improved technique based o...
متن کاملComparative Analysis of Image Denoising Methods Based on Wavelet Transform and Threshold Functions
There are many unavoidable noise interferences in image acquisition and transmission. To make it better for subsequent processing, the noise in the image should be removed in advance. There are many kinds of image noises, mainly including salt and pepper noise and Gaussian noise. This paper focuses on the research of the Gaussian noise removal. It introduces many wavelet threshold denoising alg...
متن کاملImage Steganalysis Based on Co-Occurrences of Integer Wavelet Coefficients
We present a steganalysis scheme for LSB matching steganography based on feature vectors extracted from integer wavelet transform (IWT). In integer wavelet decomposition of an image, the coefficients will be integer, so we can calculate co-occurrence matrix of them without rounding the coefficients. Before calculation of co-occurrence matrices, we clip some of the most significant bitplanes of ...
متن کاملImage Analysis Using a Generalised Wavelet Transform
The suitability of wavelet transforms (WT) for use in image analysis is well established: a representation in terms of the frequency content of local regions over a range of scales provides an ideal framework for the analysis of image features, which in general are of di erent size and can often be characterised by their frequency domain properties [1]. However, the standard form of wavelet dec...
