Haze removing from a single image is a very difficult problem. Haze is fashioned because of the two essential phenomena which might be attenuation and the air light. Attenuation decrease contrast and air light increase more light inside the region. We use color attenuation prior for dehazing single hazy image. We divide image into small sized patches. Here we discuss atmospheric scattering model,...
Renal biopsies form the gold standard of diagnostic and prognostic assessments of renal transplants. With the addition of new quantitative strategies to supplement renal biopsy interpretation such as gene array and metabolomics, the capability to incorporate all quantitative measures for clinical interpretation will require multi-dimensional analyses. Currently, renal biopsies are analyzed manually;...
Color Blindness Test Quantification using Primary Color Cluster is a color blindness test that was developed to complement the existing color blindness test nowadays. Color cluster based test aims to classify what colors that can and can not be seen by anyone with more detail. Color blindness test quantification in this thesis aims to cluster human's eyes ability to distinguish primary colors: red,...
This paper objective is to analyze LBP and CM for the comparative analysis in the field of content based image retrieval (CBIR). In this paper LBP and CM methods are used for the efficient retrieval of the images from the Wang database. All the 10 classes are used for the results comparison. LBP is used for better thresholding and CM is used with color dominant features for the efficient retrieval...
Different from traditional algorithms, the material modeling method utilizing luma Y in YUV color space has been developed in this paper. Our method, which interactively acquires material appearance from a single image, includes four main steps: removing highlight, recovering normal based on luma Y, estimating diffuse coefficient, setting glossiness and specular coefficient interactively. The experiment...
Continuous authentication offers the ability to continuously verify users' identity for accessing to the protected resource. Although current explorations such as face and fingerprint verification have seen varying rates of success, three main problems may limit their applicability in the context of information protection and access control: they can be of low availability in some practical scenarios,...
Recently, there are huge number of researches focusing on development of teaching tools to enhance learning result. However, for some courses, they require a novel system to enhance learning environment. This research focuses on geography course in the use of color and contour lines in height differentiation according to altitude terrain. We implement an augmented reality sandbox to be an interaction...
The development of intelligent systems to support maritime situation awareness is the main goal of the SEAGULL project. By equipping unmanned aerial vehicles (UAVs) with different types of optical sensors we target an intelligent maritime surveillance system. In this paper we present experiments performed with an hyperspectral camera to detect oil spills. We have developed a detection algorithm that...
This paper proposes an image-based method for product color design and constructs a color matching model on the basis of the CorelDRAW platform by establishing a reflection between the image words of colors and excellent color applications. The grey relation clustering method is applied to classify and simplify consumers' image words. Then, product color design options are found in combination with...
Intrinsic image decomposition is an important technique that decomposes an image into reflectance and shading components. In this paper, we enable intrinsic decomposition for stereoscopic images. Traditional approaches cannot be directly applied to decompose stereoscopic images, yielding inconsistent reflectance and 3D artifacts after recoloring. To solve this problem, we propose a straight yet effective...
One of the important goals in Human Computer Interaction (HCI) is designing better and more intuitive interfaces for improving the interactions. There are lots of approaches to address this problem. One of these approaches is utilizing human hand gestures. The degree of freedom and complex structure of human hand however, make capturing and modeling of hand gestures a challenging problem. In this...
The article discusses how to use the computer collecting and analyzing information of regional color. Draw a method about computer to extract regional color and establish the color analysis system. The macroscopic display of different statistics are represented and compared to essence in regional city order. The study method and train of thought can be established for urban color order reasonable...
Jigsaw puzzle is one of the brain game, which is used in many applications, such as, in archeology, biology, games, and other life issues. There are important things that fail from the setting of the puzzle it self, for example on its pieces of the jigsaw puzzle. In this paper, the researchers analyze the set of the square jigsaw puzzle that is already arranged but has one or more missing pieces....
Unmanned aerial vehicles (UAV), also referred to as drones, are a growing field in computer science with applications in military systems, delivery services, emergency relief and evacuation. One of the primary obstructions to the allowance of UAV journeys over populated areas is the lack of sophisticated automated systems that detect drone landing sites. In this paper, we propose a landing area detection...
In today's world of fast communication, to insure, the security and integrity of information is a big challenge. Data hiding also known as Steganography is one of the fields that deal in methods related information security and hide secret information and message other information. This paper elucidates the effect of data hiding in different number of least significant bits in the primary colors of...
Skin cancer is one of the most prevalent types of cancer in our world. Diagnosis of skin cancer needs specialized equipment, doctors and continuous monitoring. Patients living in remote areas normally cannot access such facilities. To overcome these barriers of access, Computer Aided Diagnostics, an emerging field in computer science, often called telemedicine, is being considered a promising approach...
A development of Human-Computer Interface (HCI) technology is proposed to estimate and investigate user's fatigue problem with non-invasive optical technique using web-camera sensor. Two kind of parameters are used such as heart rate (HR) as the physiological sign by processing the change of the skin color from face area and separating the signal color that normalized and analyzed using Independent...
Image inpainting is an active research field of image processing. Previous inpainting methods often require a long computational time to give sufficient results, especially due to the extensive search process of exemplar-based methods. This work improves a previous fast inpainting method based on local similarity, which achieves runtimes measured in tens of milliseconds per image, but often results...
Many studies of material property estimation and material recognition have been conducted. Previous approaches evaluate the validity or usefulness of hand-designed image features. Thus, we propose a method to directly and naturally acquire image features for material perception using convolutional neural networks. Using a fine-tuned network, we achieved approximately the same recognition accuracy...
Web-based laboratories are promising to save the cost required to setup a hands-on laboratory in schools. There are several basic experiments in physics which help the students understand the basics of classical physics. However, the rising cost of laboratory infrastructure and costly equipment to conduct these experiments make it difficult for schools, in developing countries like India to build...
