Recent improvements both in computing hardware and MATLAB software have made it possible to achieve temporally precise control over experiments using MATLAB ( Asaad and Eskandar 2008a Brainard 1997 Gardner and Larsson 2012 Kleiner et al. In the past, the idea of running experiments, which require millisecond-level timing precision for presenting stimuli and recording responses, in a high-level programming environment such as MATLAB was not feasible because the performance of the software was inadequate for applications requiring millisecond-level temporal performance. MATLAB is a high-level programming language that emphasizes ease of use and portability at the expense of performance (i.e., processing speed) and access to low-level hardware functions (e.g., memory management). In a number of research fields, including neurophysiology, cognitive neuroscience, and perceptual psychophysics, MATLAB has become a nearly ubiquitous tool that many investigators use extensively for data analysis. If they do have a programming background, they may not be familiar with the particular language or platform required by the experiment control software used in that laboratory. One limitation of this approach is that not all experimentalists arrive at the laboratory with a strong programming background. Finally, when working with subjects engaged in complex behaviors, the ability to create quickly and easily a wide range of tasks and to modify task parameters rapidly is essential.Ī number of software tools for controlling such experiments have been developed over the years, virtually all of which were designed to run on a specific and narrow range of hardware and software, and most required the user to program in a relatively low-level programming language (e.g., C or C++).

Third, such research requires the ability to analyze behavioral data both in real-time and in offline analysis.

Second, researchers need the ability to monitor and respond to subjects' actions. First, researchers need control over the sensory stimuli delivered to the subject. Although the exact needs of different experimental approaches can differ widely, all studies investigating perception, cognition, or action of an awake subject share a number of common requirements. Furthermore, such experiments may utilize a diversity of model organisms, ranging from insects and rodents to nonhuman primates and human subjects. The actual correction process is to design a filter to estimate pixel value of the original image from the distorted image which maximum close to the original images according to the prescribed error criterion.The ability to control precisely the presentation of sensory stimuli to subjects and to monitor their behavioral responses is critical for performing experiments in a wide range of research fields from social and cognitive psychology to systems and cognitive neuroscience. The basic idea of image correction is to establish the corresponding mathematical model based on the distortion reasons, extracting the needed information from the contaminated or distorted image signals, restore the image to its original appearance along the reverse process that distorts the image. The causes of image distortion including: aberration, distortion and limited bandwidth of the imaging system geometry distortion caused by photographic attitude and nonlinear sweep scanning of the imaging device motion blur, radiation distortion and the noise-corruption. Image correction refers to the restoration of distorted images. In the process of image generation, transmission and recording, the quality of images will decrease due to various reasons, which will lead to the degradation of the image.
