Description: The present report outlines the design, implementation and performance of the application of Hough
Transform (HT) to detect circles in arbitrary pictures.
Detecting circles in arbitrary pictures involves a two step process in this project. First, edges within the
image have to be detected then, by means of a voting mechanism the most probable circles will be
located.
Edge detection goal is to look for boundary locations that naturally happen between objects. Objects
normally have continuous intensity values therefore sudden changes in that pattern might indicate a
boundary condition. Changes of intensity in one direction can be calculated by the gradient operator
however, noise can alter meaningful edges. Convolution is then normally applied to account for a small
amount of smoothing, thus reducing noise.-The present report outlines the design, implementation and performance of the application of Hough

Description: 本篇論文提出的整合式解交錯(Integrated De-interlacing)的演算法，可以有效提昇移
動區域的畫面，但是當移動估計不正確時，反而會使移動補償後的畫面變得很差，為了
改善這種情況，因此結合移動可適性解交錯的優點，並將空間圖場內插(Spatial
Interpolation)的方式改成ELA(Edge Line Average)來設計，經過電腦模擬的結果發現，不僅在視覺上提高畫面的解析度，在某些影像峰值訊號雜訊比(Peak Signal Noise Ratio ,
PSNR)也比線平均解交 錯(Line Average De-interlacing)多出好幾分貝的畫質增益。
此外，在整合式解交錯演算法中也增加影片偵測(Film Detection)和影像加強(Image
Enhancement)的演算法設計，在這樣演算法的架構下，透過影片偵測的演算法，我們可
真實地還原3:2 Pull Down 的影片格式，而不會有鋸齒狀(Saw-Toothed)的畫面出現，而影
像加強的演算法，則可以在解交錯後，經過影像的調整，使輸出畫面呈現不同的效果，
達到消費者的需求。-The main theme of this thesis is an integrated de-interlacing system, which incorporates
several known and improved techniques in a nice manner to produce good de-interlaced image
quality. We first develop an accurate motion detector that classifies image regions into
stationary, low-motion, and high-motion categories. The simple field merging method is
applied to the stationary regions. The edge line average interpolation method is applied to the
slow-motion regions. Finally, the motion-compensated interpolation is applied to the
high-motion regions. In addition, hierarchical motion estimation and motion vector smoothing
techniques are employed to enhance the quality of estimated motion vectors. Our computer
simulation shows that the subjective image quality is improved by using the proposed scheme.
Also, its PSNR measures are better than the conventional spatial or temporal interpolation
schemes. Platform: |

Description: 摘要文中算法首先在曲线尺度空间中通过高斯平滑以消除噪声；然后再基于自适应弯曲度计算和角点筛选准
则确定角点. 该算法不需要预先输入参数，具有较好的抗干扰性，实现简单有效.
关键词高斯平滑；尺度空间；自适应；角点检测-Abstract In image processing，corner point means the dominant point of maximum curvature aiong the
bounding edge of pianar object. A method of detecting and iocaiizing corners of pianar curvature based on Gaussian
scaie space is presented. An adaptive curvature estimate method measures the significance of each point on
the boundary preprocessed by Gaussian smoothing；then a criterion is estabiished to choose the desired corner
points. The method reguires no input parameter，and experiments were performed to show that the scaie space
corner detector based on Gaussian smoothing is reiiabie for objects with muitipie-size features and noisy boundaries.
