Öz: Günümüzde mobil uygulamalar oldukça yaygın kullanılmakta, birçok kurum servislerini mobil alanlara taşımaktadır. Bu uygulamalar için diğer yazılımlardan farklı gereksinimler bulunmaktadır. Bunların en başta gelenleri bellek kısıtı ve işlemci kullanımıdır. Bellek sızıntısı olan, hızlı yanıt veremeyen uygulamalar kullanıcı memnuniyetini düşürmektedir. Kullanıcıların mobil uygulamadan kolay va...

It has become increasingly important to develop hands-free speech recognition techniques for the human-computer interface in car environments. However, severe car noise degrades the speech recognition performance substantially. To compensate the performance loss, it is necessary to adapt the original speech hidden Markov models (HMMs) to meet changing car environments. A novel frame-synchronous...

This study examined how perceptual expertise facilitates encoding and recognition. The electroencephalogram of car experts and car novices was recorded in the study as well as test phases of a remember/know task with car and bird stimuli. Car expertise influenced performance and event-related potentials (ERPs) for cars but not birds. Experts recognized and "recollected" cars more accurately, wh...

This paper presents in-car speech recognition using a modelbased Wiener filter (MBW) and multi-condition (MC) training. The MBW is a 2-step denoising algorithm based on both rough and precise estimation of speech signals. Correcting roughly estimated signals with a Gaussian mixture model (GMM) makes it possible to accurately denoise with little computational cost. In an evaluation of in-car spe...

Traffic management and security issues have become all pervasive in today’s environment. In order to regulate traffic it is necessary to identify vehicles with their registration plates. Vehicle license plate recognition technology has helped in vehicle identification, theft prevention, speed regulation, and various other traffic management concerns. With the introduction of high security regis...

The task of object recognition can be classified into two categories: generic and specific. Generic object recognition is to recognize classes of objects such as “a chair” and “a car”. Specific object recognition, on the other hand, is for identifying object instances such as a specific type of chair and car, in other words “the chair” and “the car”. This paper concerns the latter, especially m...

Due to rapid development of technology and increasing use of vehicles, license plate recognition system has numerous applications. In present world, crimes are increasing day by day with a rapid speed and criminals use vehicles in crimes. When we go at a crowded place, we see that people does not follow traffic rules during driving due to which many road accidents occur. So we have designed a l...
