Linux is a highly configurable operating-system kernel which has been widely studied in the context of software product lines over the past years. Understanding the challenges and perils of evolving and maintaining feature models of the size of Linux is crucial to provide the right tools for development today and to direct future research. Unfortunately, previous studies show contradictory obse...

In this paper, we address the stereo matching problem in the presence of reflections and translucency, where image formation can be modeled as the additive superposition of layers at different depth. Thepresenceof sucheffects violates the Lambertian assumption underlying traditional stereo vision algorithms, making it impossible to recover component depths using direct color matching based meth...

In this research paper, consists of compressing the images within each pixel before the storage processes, hence the size of the memory gets reduced. This can be done by the proposed method namely block based compression algorithm which uses the differential coding scheme. Here, differential values are captured and then quantized. The differential coding scheme uses the concept of selecting the...

Change detection studies in remote sensing operate with the notion that a quantifiable difference in an object’s spectral value, from one time period to another, represents a physical change on the ground. To confound this premise, other factors, such as atmospheric conditions and illumination geometry, can influence an object’s spectral response. For this reason, a common first step in digital...

Steganalysis is the method used to detect the presence of any hidden message in a cover medium. A novel approach based on feature mining on the discrete cosine transform (DCT) domain, markov process based approach for modeling the difference JPEG 2-D arrays, machine learning for steganalysis of JPEG images which prevents cross validation is proposed. The neighboring joint density and absolute n...

Information security is very important task in the field of information and communication technology. Encryption is one way to secure information. In this paper we present combined concept of pixel and position manipulation technique for image encryption. The proposed technique involves three stages. In first stage pixel position manipulation is done by using pixel shuffling block where index v...

The Land use/ Land cover change in urban areas and the difference of the earth surface after the flood can be detected from remote sensing images by performing image differencing algorithms. Although many algorithms were proposed to generate difference images, the results are inconsistent. In order to integrate the merits of difference algorithms, fusion techniques are used to merge multiple di...

We describe and characterize an experimental system to perform shape measurements on deformable objects using high-speed close-range photogrammetry. The eventual application is to extract the kinematics of several marked points on an insect wing during tethered and hovering flight. We investigate the performance of the system with a small number of views and determine an empirical relation betw...
