In today’s digital world, image edge detection is widely used in all over the globe. Digital image edge detection is used to detect the sharp changes in brightness of the images and the edge of a digital image. There are many classical... more
Image compression technique is used in many applications for example, satellite imaging, medical imaging, video where the size of the iamge requires more space to store, in such application image compression effectively can be used. There... more
This paper aims to analyze the heart electrocardiograph (ECG) to diagnose the heart performance and predict any future complications. The authors utilize the MIT BIH database to obtain the original data. The discrete wavelet transform... more
Digital social platform increase the importance of image in daily life. Hence privacy of content plays an important role when content get live, so data owner put signature inform of watermark for claiming its proprietorship. This work has... more
Face image is an efficient biometric trait to recognize human beings without expecting any cooperation from a person. In this paper, we propose HVDLP: Horizontal Vertical Diagonal Local Pattern based face recognition using Discrete... more
The goal of this paper is to detect the breast cancer using neural networks. Image processing techniques play an important role in the diagnostics and detection of diseases and monitoring the patients having these diseases. Breast Cancer... more
En este trabajo, se desarrolló una interfaz en MatLab preparada para cuantificar de manera sistemática el desempeño de distintos algoritmos para reconstruir imágenes médicas obtenidas por ultrasonido. Los filtros seleccionados... more
Steganography is the art of covered or hidden writing. The main purpose of steganography is covert communication-to hide the existence of a message from a third party. Steganography is generally used to hide important information in a... more
In image processing one of significant perspective is the image compression. It is concerned in reducing the quantity of fundamental element to represent of an image. An immense memory and high data transfer capacity are required for... more
2 F. Abramovich, Т. С. Bailey and T. Sapatinas mathematical and algorithmic techniques used in statistics, did not originate from statisticians, nor with statistical applications in mind. The wavelet transform is a synthesis of ideas... more
Currently, Video steganography is especially used for the aim of secure digital communication. This is often the art of hiding all the information in between sender and receiver through carrier like graphics, documents, videos and... more
The information security has become one of the most significant problems in data communication. So it becomes an inseparable part of data communication. In order to address this problem, cryptography and steganography can be combined.... more
ABSTRACT Digital media is the need of a people now a day as the alternate of paper media. As the technology grown up digital media required protection while transferring through internet or others mediums. Watermarking techniques have... more
In order to contribute to the security of sharing and transferring medical images, we had presented a multiple watermarking technique for multiple protections; it was based on the combination of three transformations: the discrete wavelet... more
With the growth and advances in digital communication technologies, digital images have become easy to be delivered and exchanged. These forms of digital information can be easily copied and distributed through digital media. These... more
A pilfered duplicate of a digital video would be easily disseminated to the global audience because of the rapid high-speed internet. Due to impeccably replicable nature of digital video, numerous unlawful duplicates of the original video... more
