with the rapid emergence of 3d applications and virtual environments in computer systems; the need for a new type of interaction device arises. this is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. in other words, evolution of user interfaces shapes the change in the human-computer interaction (hci). in...

Automatic recognition of speech emotional states in noisy conditions has become an important research topic in the emotional speech recognition area, in recent years. This paper considers the recognition of emotional states via speech in real environments. For this task, we employ the power normalized cepstral coefficients (PNCC) in a speech emotion recognition system. We investigate its perfor...

In order to facilitate the entry of data into the computer and its digitalization, automatic recognition of printed texts and manuscripts is one of the considerable aid to many applications. Research on automatic document recognition started decades ago with the recognition of isolated digits and letters, and today, due to advancements in machine learning methods, efforts are being made to iden...
