To improve this image quality, we use the improved Poisson maximum a post...

Recognition of the pitch of a tone is disrupted by the interpolation of other tones during the retention interval. The disruptive effect of an interpolated tone varies systematically as a function of its pitch relationship to the tone to be remembered, and is maximal at a ⁄3-tone separation. When such a tone is interpolated, the interpolation in addition of a further tone that is ⁄3 tone remove...

The effect of the time of presentation of an interpolated stimulus on dynamic memory for pitch of pure tones of 900-2000 Hz was investigated by comparison of successive stimuli. The test tone followed the sample tone after 25, 40, 60, 80, 160 or 320 s. The interpolated stimulus (a pure tone of 220 Hz) was timed either 20 s before the test tone (Experiment I) or 20 s after the sample (Experiment...

Pigeons and humans were trained to discriminate between pictures of three-dimensional objects that differed in global shape. Each pair of objects was shown at two orientations that differed by a depth rotation of 90 degrees during training. Pictures of the objects at novel depth rotations were then tested for recognition. The novel test rotations were 30 degrees, 45 degrees, and 90 degrees from...

This paper presents a novel adaptive interpolation method for digital images. This new method can reduce drarnatically the blurring and jaggedness artifacts on the high-contrast edges, which are generally found in the interpolated images using conventional methods. This high performance is achieved via two proposed operators: a fuzzy-inference based edge preserving interpolator and an edge-shif...

Multi-image interpolation in space and time has recently received considerable attention. Typically, the interpolated image is synthesized by adaptively blending several forward-warped images. Blending itself is a low-pass filtering operation: the interpolated images are prone to blurring, even if correspondences are perfect. Furthermore, ghosting artifacts appear as soon as the underlying corr...

We describe a simple variant of the interpolated Markov model with non-emitting state transitions and prove that it is strictly more powerful than any Markov model. Empirical results demonstrate that the non-emitting model outperforms the interpolated model on the Brown corpus and on the Wall Street Journal under a wide range of experimental conditions. The nonemitting model is also much less p...

The assessment of defibrillation (DFT) efficacy has long been the standard of care during defibrillator implantation. To ensure an acceptable DFT safety margin, early defibrillator systems frequently required that the shock polarity and the location, type, or number of electrodes had to be altered. Advances in defibrillator and lead technology have resulted in lower and more consistent DFT thre...
