On-Orbit Modulation Transfer Function Estimation Based on the Refined Image Kernel [PDF]
To overcome the limitations of traditional on-orbit modulation function transfer (MTF) measurement methods that are heavily dependent on natural features, scenery, artificial edges, and point source targets, this paper presents an on-orbit MTF ...

The modulation transfer function for speech intelligibility. [PDF]
We systematically determined which spectrotemporal modulations in speech are necessary for comprehension by human listeners. Speech comprehension has been shown to be robust to spectral and temporal degradations, but the specific relevance of particular ...

Modulation Transfer Function Analysis in Myopic Model Eye
Hitherto, the eye modelling is based on the emmetropic eye taken its ocular optical components value from the population-based studies. However, no studies have been done to study the effect of aberration of myopic refractive error by modelling the eye ...

Line-Based Modulation Transfer Function Measurement of Pixelated Displays
This paper proposes a line-based method for measuring the modulation transfer function (MTF) of a display. In this method, the spatial distribution of a single line that is displayed in a small region of the screen is analyzed.

Measurement of the optical transfer function using a white-dot pattern presented on a liquid-crystal display [PDF]
The optical transfer function (OTF) and its modulus, the modulation transfer function (MTF), are widely accepted measurements of the quality of optical systems. There are different ways of estimating both OTF and MTF. Random-dot-pattern methods have some
