This paper exhibits high definition picture era in single picture super resolution technique for enhancing the resolution of natural pictures. High definition picture plays a crucial role in recognition and recognizable proof of components in a wide range of pictures where high definition capture of picture is troublesome but essential. This article addresses high definition picture development by...
The advent of efficient short range radio communication coupled with advancement in miniaturization of computing devices has enabled the development of wireless multimedia sensor network (WMSN). Energy is one of the scarcest resources in such networks, especially it is scarce in transmitting multimedia data. This work presents an energy-saving image compression scheme. The nodes in WMSN are equipped...
We present a scalable system for sketch-based image retrieval (SBIR), extending the state of the art Gradient Field HoG (GF-HoG) retrieval framework through two technical contributions. First, we extend GF-HoG to enable colorshape retrieval and comprehensively evaluate several earlyand late-fusion approaches for integrating the modality of color, considering both the accuracy and speed of sketch retrieval...
Demosaicing is the process of interpolating the output from a single chip colour filter array sensor to form a full colour image. In hardware, the simplest algorithms: zero order hold and bilinear interpolation, are commonly used because of their simplicity and low resource requirements. State of the art algorithms are difficult to implement in hardware because of their complex access patterns. This...
A single-shot multispectral camera equipped with a filter array has the potential to promote a fast and low-cost multispectral imaging system. We focus on the design of a multispectral filter array and demosaicking in this paper and propose a pathology-specific multispectral imaging system. The spectral sensitivities and patterns of the filter array are optimized by using training data of real pathological...
In depth-image-based rendering (DIBR), a new virtual viewpoint image is synthesized by mapping color pixels from one or more reference views to the new image grid using corresponding disparity values. However, due to necessary roundings to the 2D grid, "rounding holes" appear in synthesized objects, which are typically filled using local interpolation. In this paper, leveraging on a recent...
Single-sensor color cameras, which classically use a color filter array (CFA) to sample RGB channels, have recently been extended to the multispectral domain. To sample more than three wavelength bands, such systems use a multispectral filter array (MSFA) that provides a raw image in which a single channel level is available at each pixel. A demosaicing procedure is then needed to estimate a multispectral...
Existing approaches to camera model identification frequently operate by building a parametric model of a camera component, then using an estimate of these model parameters to identify the source camera model. Since many components in a camera's processing pipeline are both complex and nonlinear, it is often very difficult to build these parametric models or improve their accuracy. In this paper,...
Edit propagation is a class of algorithms that propagates user-specified color adjustments across an image or video. The user-specified adjustments take the form of sparse paint strokes that give examples of the desired alterations. Existing edit propagation (EP) algorithms are based on color similarity, and thus will alter all objects that have a similar color. In this work, we describe an EP algorithm...
This paper proposes a fuzzy-rule-embedded reduction image construction method for image enlargement. A fuzzy rule is generated by considering distribution of pixel value around a target pixel. The generated rule is embedded into the target pixel in a reduction image. The embedded fuzzy rule is used in a fuzzy inference to generate a highly magnified image from the reduction image. Experimental results,...
In this paper, we present a method to accomplish free viewpoint video for soccer scenes. This will allow the rendering of a virtual camera, such as a virtual rail camera, or a camera moving around a frozen scene. We use 7 static cameras in a wide baseline setup (10 meters apart from each other). After debayering and segmentation, a crude depth map is created using a plane sweep approach. Next, this...
Image cloning which could copy the source image and “paste“ it into the target image seamlessly is one of an important digital image manipulation technique. Traditional methods to cope with this problem were to analyze image information in gradient domain according to solving Poisson equations. As a result, existing methods need high computational cost and memory usage which hinder them from real-time...
The paper is devoted to the problem of information capacity of human-computer interface. The author suggests the new method of calculation for radial basis functions. This method could significantly decrease complexity of calculations. New type of blending functions - blending functions of orthogonal basis is offered. These suggestions allow constructing the model of complex 3D objects in a real time...
The present paper proposes a new method for color image demosaicing. This method separates luminance from chrominance and allows luminance to be extracted directly from known pixel values. Since interpolation for missing pixels is applied only to chrominance channels, it can reduce artifacts. Moreover, in chrominance channels the proposed method tries to interpolate pixels along edges. As consequence,...
Digital cameras have become the most important imaging devices in all kinds of Hand-held devices. In these devices, the quality of image reconstruction is an important indicator of the overall quality of the end-user experience image, and the image resolution is a mainly parameter of Digital cameras. Usually, only incomplete color information of the scene is measured at each pixel location by the...
This paper presents a reversible fragile watermarking scheme for the authentication of demosaicked images. Each authentication code is embedded into the two rebuilt components of each color pixel by using a designed authentication table (ACT). The utilization of ACT secures the watermarking procedure and the watermarked image can be recovered back to the original demosaicked image by the proposed...
Weeds are among the most significant and costly environmental threats in Australian agriculture. The distribution, size, density and species of weeds are often heterogeneous in cropping lands. Instead of uniformly spray the same type of herbicide to a whole farm land, using weed maps to do selective spray can reduce herbicide usage and therefore can reduce the serious problems of herbicide resistance,...
There are numerous trading systems in use today that are focused on profiling the customers, so they can adapt to their expectations. The presented system in this article works on similar principles. Its primary goal is to examine how the events affect each other, so it can create a list related to the search. Soft computing methods are used to create the profile. The first profile is created from...
We propose the technique of the semi-automatic image creation. By this we mean an automatic completion of an image that is partially defined on the given domain. The essential feature of this technique is that the complementary area is much larger than that where the image is defined. Moreover, the proposed technique can be used in image upsampling, image inpainting, etc. In this contribution, we...
In this paper, we propose a novel, fully automatic method to obtain accurate view synthesis for soccer games. Existing methods often make assumptions about the scene. This usually requires manual input and introduces artifacts in situations not handled by those assumptions. Our method does not make assumptions about the scene; it solely relies on feature detection and utilizes the structures visible...
