This paper deals with an adaptive general scale interpolation algorithm that is capable of arbitrary scaling factors considering the non-stationarity of natural images. The proposed AR terms are modeled by pixels with their adjacent unknown HR neighbors. A novel stereo matching algorithm is proposed that utilizes color segmentation on the reference image and a self-adapting matching score that ...

This work proposes a structural enhancement and new technique to design the loop filter (LF) of third-order phase-locked (PLL) enhance PLL dynamic performance under abnormal grid conditions. The proposed combines moving average (MAF) an arbitrarily delayed signal cancelation (ADSC) for achieve DC-offset rejection harmonics elimination. window length MAF is selected be one-sixth fundamental peri...

This paper proposes a traffic policing mechanism for multimedia communication systems with quality of service guarantees, called Slotted Moving Window (SMW). Moreover, it also presents efficient implementations of SMW and several other well known traffic policing mechanisms, ...

This paper provides a new and fast method for matching and recognition of characters in Arabic license plate images. For this purpose, various methods have been proposed in literature. However, most of them suffer from: sensitivity to non-uniform illumination distribution, existence of shade in license plate, license plate color and the need for receiving an exact image of the license plate. Th...

Let X be a random variable taking values in a function space F, and let Y be a discrete random label with values 0 and 1. We investigate asymptotic properties of the moving window classification rule based on independent copies of the pair (X,Y ). Contrary to the finite dimensional case, it is shown that the moving window classifier is not universally consistent in the sense that its probabilit...

In 2 experiments, a new technique called the auditory moving window was used to investigate aspects of spoken-language processing. Participants paced their way through spoken sentences divided into word or wordlike segments, and their processing time for each segment was recorded. The 1st experiment demonstrated that high-frequency words in spoken sentences require less time to process than do ...

Background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. Several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

PURPOSE To investigate the dosimetric accuracy of the sliding window gated IMRT compared with the static treatment, using varying dose rates. MATERIALS AND METHODS This study measured changes in output and diode array response with changing dose rate, verified the precision of the motion table, and measured changes in dose distribution accuracy with film and diodes at two depths with changing...
