Detection of divergence in optical flow fields
Psychophysical thresholds for the detection of divergence (expansion and contraction) in the presence of a translational component are determined. Stimuli consist of sparse random dot patterns. Lifetime, number of dots, divergence, and translational velocity are varied over a wide range. Moreover, the two major characteristics of a divergence pattern, namely, the direction of and the velocity a...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

valuable as a source of spatial information. Current techniques provide flow fields which are noisy and sparse, mak ing the recovery of spatial proper ties difficul t at best. This paper describes a technique for locating discontinuities in optical flow, which typically correspond to object boundaries. A simple blurring interpolator is used to smooth out noise and produce denser fields. Discont...
متن کاملUsing Optical Flow Fields for Polyp Detection in Virtual Colonoscopy
Since the introduction of Computed Tomographic Colonography (CTC), research has mainly focused on visualization and navigation techniques. Recently, efforts have shifted towards computer aided detection (CAD) of polyps. We propose a new approach to CAD in CT images that attempts to model the way a radiologist recognizes a polyp using optical flow fields (OFF). Features extracted from OFFs are u...
متن کاملTurbulence in Optical Flow Fields
In this thesis I will examine the relations between turbulence as found in physical systems and turbulence in optic ow elds. I will record some image sequences of a theoretically well understood turbulent physical system and from these image sequences I will examine the relations between the optic ow of the image sequences and the physical parameters of the turbulent system. I will examine the ...
