Point spread function measurements for underwater imaging: an analysis of wavelength-specific behavior for image deconvolution.

Underwater optical imaging, especially in coastal waters, suffers from reduced spatial resolution and contrast by forward scattered light. With the increased number of hyper- and multi-spectral imaging applications, the effect of the point spread function (PSF) at different spectral bands becomes increasingly more relevant. In this work, extensive laboratory measurements of the PSF at 450, 500, 550, 600 and 650 nm in different turbidity have been carried out.

The Eyelink Toolbox: eye tracking with MATLAB and the Psychophysics Toolbox.

The Eyelink Toolbox software supports the measurement of eye movements. The toolbox provides an interface between a high-level interpreted language (MATLAB), a visual display programming toolbox (Psychophysics Toolbox), and a video-based eyetracker (Eyelink). The Eyelink Toolbox enables experimenters to measure eye movements while simultaneously executing the stimulus presentation routines provided by the Psychophysics Toolbox.
