The capability of Kasuba’s Simplified Fuzzy ARTMAP (SFAM) to behave as a Pattern Recognizer/Classifier of images both noisy and noise free has been investigated in this paper. This calls for augmenting the original Neuro–Fuzzy model with a modified moment-based RST invariant feature extractor. The potential of the SFAM based Pattern Recognizer to recognize patterns — monochrome and color, noisy...

This paper covers a method for capturing documents using a digital camera. A typical cheap VGA digital camera (resolution 640 by 480 pixels) does not have adequate resolution to capture text over a page. By displacing the sensor spatially and taking multiple acquisitions we seek to enhance the resolution. There are many approaches in the literature to multi-frame reconstruction. Our approach di...

The present experiment was designed to examine the roles of painted linear perspective cues, and the convexity bias that are known to influence human observers' perception of three-dimensional (3D) objects and scenes. Reverse-perspective stimuli were used to elicit a depth-inversion illusion, in which far points on the stimulus appear to be closer than near points and vice versa, with a 2 (Type...

We create a computer based numerical model to predict the color spectra of printed patches on dry toner electrophotographic printers. The goal of this research is to obtain a simplified model describing the input-output behavior of the printers based on the physical characteristics of the different printing process steps and the interactions between them. This leads to a better understanding of...

Large, bold marks are painted or incised on the handles or bases of thirty-seven pictorial vases. These same kinds of marks and same patterns of marking are found on non-pictorial Mycenaean pottery. In general, marks on Mycenaean pottery are rare and the circum­ stances of their use are not yet fully understood. It is clear that they are associated with Cyprus, and it is most likely that they a...

Division-of-focal-plane (DoFP) polarization image sensors allow for snapshot imaging of linear effects with inexpensive and straightforward setups. However, conventional interpolation based reconstruction methods such produce unreliable noisy estimates quantities as Degree Linear Polarization (DoLP) or Angle (AoLP). In this paper, we propose a demosaicking algorithm by inverting the formation m...
