Methods 80 eyes of 40 cases with high myopia (-7.00D～-9.00D) who received lasik, it made the corneal flap using Moria M 2.They were divided 3 groups for different corneal curvature, different of Moria carriago-Barraguerm icrokeratome, different knife with new or old, The pre-LASIK and post-lasik refactive diopter, visual acuity and residual stromol thickness were compared.
Results The eyesight of children was significantly improved after operation(P<0.01). The eyes of corrected vision exceeding 0.3 and 0.05 after 1 year accounted for 83.3 %, 100%, respectively. The eyes with fusion function and stereovision accounted for 39.6 %,18.8 %, respectively.
Geometric Fourier Analysis for Computational Vision
The recognition of 3-D objects is quite a difficult task for computer vision systems.
Due to these favorable characteristics, the processed images turn much clearer and smoother, meanwhile, their significant details are kept, which results in appealing vision.
Although computer stereo vision techniques for collecting parameters of a single stem shape are comparative, complicated, and expensive, research indicates the efficiently and feasibility of close-range photogrammetry for stem image information.
Methods of computer vision, image processing and wavelet analysis technology were used to compress, filter, segment, abate noise and capture the outline of the picture.
A simulated example is also given to show the visual performance of the estimations.
The copolyimides were characterized by Infra-red (IR), Nuclear Magnetic Resonance (NMR), Gel Permeation Chromatography (GPC), Ultraviolet Visual (UV-Vis), Thermogravimetic Analysis (TGA) and Dynamic Mechanical Analysis (DMA).
By using Visual C++ programming to simulate the performance, the result indicates that when code length N = 3,072 and code rate R = 1/3, the difference with the Shannon limit is about 2 dB.
The purpose of this paper is to improve the performance and robustness of VAD by introducing visual information.
Meanwhile, data-driven linear transformation is adopted in visual feature extraction, and a general statistical VAD model is designed.
