Single late rice information extraction based on change detection method using neighborhood correlation images
Over the past several decades, moderate-resolution remote sensing data have been used to obtain regional-scale land-cover information. Nowadays Change detection has been widely used in many applications. Change detection techniques…
High capacity and robust speech data hiding in colour images
Steganography is a method for hiding information in a host signal. The host signal can be a still image, speech or video and the message signal that is hidden in the…
Water mapping through Universal Pattern Decomposition Method and Tasseled Cap Transformation
Advances in remote sensing paved a way to understand the landuse and landcover features from the eye of space borne sensors. Spectral indices are used to analyze these features. This…
A new approach for measuring 3D digitalized rape leaf parameters based on images
At present, measurement method of crop leaf area mainly proceeds in two-dimensional way, which may lead to certain degree of damage. Therefore, it will be of great significant to propose…
Lightweight forensic video watermarking to enable premium content consumption on mobile devices
Content owners are reluctant to deliver premium content to open devices due to the risk of piracy and the corresponding potential for loss of revenue. To lift this deadlock, there…
Simulation of resistive grid image filters with Jacobi iteration method for FPGA implementation
It is well known that resistive grid structures yield exponentially decreasing spatial impulse response yielding a spatial frequency response similar to that of a Gaussian filter, hence used as smoothing…
Comparison of unsupervised segmentation methods for surficial materials mapping in Nunavut, Canada using RADARSAT-2 polarimetric, Landsat-7, and DEM data
In this paper, unsupervised segmentation methods are investigated for surficial materials mapping in Nunavut, Canada. Different satellite data sources including RADARSAT-2 polarimetric image, LANDSAT-7 image, and DEM data are combined and three…
Automatinc synchronization of stereoscopic video for 3DTV broadcasting system
This paper proposes an algorithm to automatically detect synchronization error that can be occurred in the stereoscopic video system. Specially, this paper is aiming toward 3DTV broadcasting system that requires…
Periodicity detection in lifelog data with missing and irregularly sampled data
Lifelogging is the ambient, continuous digital recording of a person’s everyday activities for a variety of possible applications. Much of the work to date in lifelogging has focused on developing sensors, capturing…
