Reverse time migration (RTM) has been a popular method in industry duo to its ability of imaging complex subsurface and no dip restriction. However, RTM based on full matric capture (FMC) data is limited by the cost calculation cannot be widely used. In this study, new strategy using plane wave proposed. Plane reverse (PWRTM) does not need stack results from multiple sources directly uses as so...

The advent of machine learning techniques and image processing has led to new research opportunities in this area. Machine enabled automatic extraction analysis information from images. convergence with is useful a variety security applications. Image plays significant role physical as well digital security. Physical applications include homeland security, surveillance applications, identity au...

purpose: to present a new reliable and accurate iris recognition method applicable in identification systems. methods: the system was implemented and tested on 876 standard iris images (daugman iris images database) from 876 persons of different nationalities via image processing techniques. results: false accept reject (far) and false reject reject (frr) were smaller in our suggested method as...

Streaming of digital media makes 70% of internet traffic, and is projected to reach 80% by 2020 (CIS, 2015). However, it has been challenging for existing commercial compression algorithms to adapt to the growing demand and the changing landscape of requirements and applications. While digital media are transmitted in a wide variety of settings, the available codecs are “one-size-fits-all”: the...

Artistic style transfer has long been an interesting topic in computer vision research. Recently several methods for style transfer based on convolutional neural networks have been proposed. This project aims at understanding and implementing some of the existing methods. More specifically we succeed in implementing the optimization based neural algorithm as well as the real-time style transfer...

When changes occur in complex images that involve minute details, it is usually a daunting task to track the changes that may have occurred between two time periods. We will be presenting a method for identifying these changes through digitizing; anchoring, reorienting and subtracting, successive images, and compiling an animated sequence of image difference that will include only the changes. ...

Background: Distribution of radiographic images in the outpatient setting on compact discs-recordable (CD-R) iscommonplace. Opening, manipulating and interpreting these can be challenging. This study evaluated the availabilityand ease of use of CD-R to evaluate digital images in an outpatient orthopedic setting.Methods: 118 CD-R containing diagnostic studies were evaluated by ...

Histopathology whole slide images (WSIs) can reveal significant inter-hospital variability such as illumination, color or optical artifacts. These variations, caused by the use of different protocols across medical centers (staining, scanner), strongly harm algorithms generalization on unseen protocols. This motivates development new methods to limit loss generalization. In this paper, enhance ...
