In vision science the currently most popular models for depth perception are weak fusion models in which the final depth estimate results from a weighted average of the independent depth estimates obtained from each cue [2]. In these models a more reliable cue has a larger weight in the combined estimate. Furthermore, recent studies report that human observes combine depth cues as to obtain the...

Slant Correction is an important component of an Optical Character Recognition (OCR) system. The stronger the slant correction algorithm, the better the OCR system’s performance. In this work, a non-uniform slant estimation algorithm is presented. The algorithm uses the generalized projections of the word image. The algorithm is simple and robust. To evaluate the efficacy of the algorithm, imag...

The ductile fracture behavior of a high strength steel is addressed in this two-part study using micromechanics-based approach. objective Part II to propose, identify, and validate numerical model based on the Gurson–Tvergaard–Needleman model. This enhanced by Nahshon–Hutchinson shear modification combination with generalization Thomason coalescence criterion within fully nonlocal form relying ...

Observers judged the apparent signs and magnitudes of surface slant from monocular textured images of convex or concave dihedral angles with varying fields of view between 5 degrees C and 60 degrees C. The results revealed that increasing the field of view or the regularity of the surface texture produced large increases in the magnitude of the perceptual gain (i.e., the judged slant divided by...

This paper presents a digits classification system to recognize telephone numbers written on signboards. Candidate regions of digits are extracted from an image through edge extraction, enhancement and labeling. Since the digits in the images often have skew and slant, the digits are recognized after the skew and slant correction. To correct the skew, Hough transform is used, and the slant is c...

We measured monocular judgements of the slant of a cube face while varying eye position in the absence of stereoscopic and external lighting cues. Errors were found to be small, only 10% on average of the cube's eccentricity. Two factors appear to have contributed approximately equally to this error: an underestimate of cube slant as seen by the eye and an underestimate of eye position. When pr...

Perceived slant produced by size disparities in random-dot displays was measured by tactile matching. For a 60 deg surface, slant produced by vertical-size disparity (the induced effect) was opposite to that produced by horizontal-size disparity. Overall-size disparity produced a little slant. With small displays, effects of horizontal and vertical disparities were reduced but not those of over...

Visuomotor localization in the presence of slant was measured. Five subjects pointed at the center LED of an array of five LEDs viewed monocularly. Pointing was open-loop. The LEDs were separated by 1.5, 3.0, or 4.5 cm. The array was rotated about a vertical axis coincident with the center LED to slant the array from -50 degrees to +50 degrees. LED separation had no effect. A small linear relat...
