Singular value decomposition based matrix surgery
Jehan Ghafuri, Sabah Jassim
This paper aims to develop a simple procedure to reduce and control the condition number of random matrices, and investigate the effect on the persistent homology (PH) of point clo…
Artificial Image Tampering Distorts Spatial Distribution of Texture Landmarks and Quality Characteristics
Tahir Hassan, Aras Asaad, Dashti Ali +1
Advances in AI based computer vision has led to a significant growth in synthetic image generation and artificial image tampering with serious implications for unethical exploitati…
Secure Steganography Technique Based on Bitplane Indexes
Alan Anwer Abdulla, Sabah A. Jassim, Harin Sellahewa
This paper is concerned with secret hiding in multiple image bitplanes for increased security without undermining capacity. A secure steganographic algorithm based on bitplanes ind…
Stego Quality Enhancement by Message Size Reduction and Fibonacci Bit-Plane Mapping
Alan A. Abdulla, Harin Sellahewa, Sabah A. Jassim
An efficient 2-step steganography technique is proposed to enhance stego image quality and secret message un-detectability. The first step is a preprocessing algorithm that reduces…
Efficient High Capacity Steganography Technique
Alan Anwer Abdulla, Sabah A. Jassim, Harin Sellahewa
Performance indicators characterizing modern steganographic techniques include capacity (i.e. the quantity of data that can be hidden in the cover medium), stego quality (i.e. arti…
Steganography Based on Pixel Intensity Value Decomposition
Alan Anwer Abdulla, Harin Sellahewa, Sabah A. Jassim
This paper focuses on steganography based on pixel intensity value decomposition. A number of existing schemes such as binary, Fibonacci, Prime, Natural, Lucas, and Catalan-Fibonac…
Improving embedding efficiency for digital steganography by exploiting similarities between secret and cover images
Alan A. Abdulla, Harin Sellahewa, Sabah A. Jassim
Digital steganography is becoming a common tool for protecting sensitive communications in various applications such as crime(terrorism) prevention whereby law enforcing personals…
