Zero padding an image increases its size while keeping the total information the same, thus increasing contrast. Padding with zeros adds a constant DC component along both axes, increasing signal strength.
The MATLAB code DIP.m transforms an image from right to left by multiplying by (-1)(x+y) to centralize the Fourier spectrum, taking the DFT, conjugate, inverse DFT, and multiplying again by (-1)(x+y) to normalize.
Filtering an image with a low pass filter then high pass filter retains some high frequency data, showing the shape of an object. The opposite order retains low frequencies, like a bright ring. Butterworth filters lose more data than Gaussian due to a st
Ejection fraction is one of the important measure of the health of heart. EF can be calculated from the 2D images of Echocardiogram using Image processing techniques.
Estimation of body mass distribution using projective imageSuhas Deshpande
This document discusses using image processing techniques to estimate body mass distribution and assist in obesity diagnosis. It presents an overview of objectives, definitions of obesity, current diagnosis methods, and how image processing and MATLAB code can be used to extract measurements from images to calculate diagnostic parameters like body volume, density, and fat percentage. Initial analysis is conducted to verify the image processing methodology. The process of acquiring, calibrating, processing images and extracting measurements is explained. Results show body measurements can be estimated from images to help with obesity diagnosis.
This document discusses various techniques for measuring blood flow, including electromagnetic methods, thermal methods using thermistors or hot wires, ultrasound using implantable CMUT arrays, and tracer dyes. It also describes designs for photoplethysmograph probes and analyzing blood flow using thermal modeling and heat transfer analysis. Finally, it mentions a biotelemetry system that was implanted in sturgeon to measure blood flow and temperature using an implantable Doppler flow meter and wireless data transmission to an external base station.
The document discusses human balance and postural control. It describes how the vestibular system in the inner ear along with vision, proprioception, and the central nervous system work together as a feedback system to maintain balance. Common balance disorders are related to problems in the ear or brain. Balance can be assessed using tests like posturography, which measure a person's balance responses under different sensory conditions, or electronystagmography to detect involuntary eye movements related to inner ear problems. Research aims to apply understanding of human balance mechanisms to areas like humanoid robotics and studying balance in microgravity.
Super Effective Denial of Service AttacksJan Seidl
The document discusses denial-of-service (DoS) attacks and their targets at different layers of the OSI model. Layer 3 attacks target bandwidth consumption through techniques like ping floods and SYN floods. Layer 7 attacks target application resources through vectors like SSL handshake renegotiation to cause intense CPU usage on the server. The document outlines how Layer 7 attacks are more stealthy and efficient at causing damage than Layer 3 attacks.

Telesurgery involves performing surgical procedures remotely using robotic systems. A surgeon controls robotic arms and instruments to operate on a patient located elsewhere. The first telesurgery was performed in 2001 between France and New York using the da Vinci surgical system. This system uses a master-slave setup with the surgeon seated at a console controlling multiple robotic arms with instruments and an endoscope through hand controls and foot pedals. Sensors provide the surgeon with force feedback, and networks with low latency are required to transmit video and control signals for telesurgery.
The document describes the Jericho Attack Technique for launching distributed denial-of-service (DDoS) attacks using public SOCKS proxies, TOR instances, and load balancing software. The technique involves binding multiple sockets from different proxy/TOR resources to a target system and load balancing the connections through programs like HAProxy. This allows evading connection limits, hiding the origin of attacks, and efficiently launching low-bandwidth Layer 7 DDoS attacks in a distributed manner. Instructions are provided on setting up socat tunnels through proxies/TOR, configuring HAProxy for load balancing, and modifying hosts files to point targets to the local system.
This document provides an overview of fingerprint identification systems, including their history, components, and applications. It discusses the types of fingerprints and how they are sensed and matched using algorithms. Fingerprint identification has been used for centuries for transactions and is now widely used in government and commercial applications, with systems integrated onto chips. Challenges include handling poor quality images and certain medical conditions, while companies produce sensors, algorithms, and full biometric solutions.
Blood pH is tightly regulated in the human body and generally lies between 7.3-7.5. pH monitoring is important in medical diagnosis and treatment, including for major diseases, surgeries, and drug effects. Various methods exist for measuring pH, including glass electrodes, metal-metal oxide electrodes, pH sensitive FETs, conductimetric sensors, and fiber optic sensors. Each method has advantages and limitations for different applications such as invasiveness, accuracy, and ability for continuous monitoring. Temperature also affects pH measurement so calibration is required.
Catch-me if you can - TOR tricks for bots, shells and general hackingJan Seidl
The TOR network is widely known nowadays but there's plenty of gold in there that is not. This talk is about everything TOR: Popping shells, tunneling tools and commanding your bots over the world's most popular darknet.
