A Note on Notation
Hyperspectral data is often expressed many ways to better describe the
mathematical handling of the data mainly as a vector of pixels when
referring to the data in a space or a matrix of pixels when referring to
data as an image.

MyBayes
2.编写两类正态分布模式的贝叶斯分类程序。
设以下模式类别具有正态概率密度函数:
ω1:{(0 0)T, (2 0)T, (2 2)T, (0 2)T}
ω2:{(4 4)T, (6 4)T, (6 6)T, (4 6)T}
(1)设P(ω1)= P(ω2)=1/2,求这两类模式之间的贝叶斯判别界面的方程式。
(2)绘出判别界面。
3.已知服从正态分布的两类训练样本集分别为
:,,,,
:,,,
,试问属于哪一类?
4.设有两类一维模式,每一类都是正态分布,两类的均值和均方差分别为,;,。
采用(0-1)损失函数,且。
(1)试绘出两类模式的密度函数曲线,其判别界面位于何处?
(2)若已获得样本:-3,-2,1,3,5,试判断它们各属于哪一类。(bayes ,matlab)

SURF-based-image-stitching
SURF算法作为一种新近出现的特征提取方法,在重复度、独特性、鲁棒性3个方面,均超越或接近以往提出的同类方法,并在计算效率上具有明显的优势。本代码采用SURF算法检测图像并进行坐标变换与图像拼接。
采用SURF算法对图像进行检测,其主要是用Hessian矩阵对图像进行检测,对图像的特征提取之后找到图像的特征点。之后采用最近临快速匹配(NN)、随机抽样一致性(RANSAC)算法和最小二乘法参数优化(LM)对特征点进行提纯匹配。最后在两幅图像中进行坐标变换,达到统一坐标系和图像拼接的效果。
(SURF(Speeded Up Robust Features) as a method of feature extraction which newly appeared is over or nearly previous method on duplication, uniqueness, and robustness and have a clear advantage on computational efficiency. This code uses the SURF and coordinate transformation algorithm to detect image and image matching.
This code uses the SURF algorithm of image detection, the main is to use the Hessian matrix of image for testing, to find the image after image feature extraction of feature points. After we used Nearest Neighbor (NN), Random Sample Consensus (RANSAC) algorithm and least square parameter optimization for purification of matching feature points. Coordinate transformation in the last two images, to coordinate system to achieve the same image stitching.

ImproveCanny
一个改进的自适应canny算法,该方法采用改进的开关型中值滤波器对图像做去噪工作,再把整幅图像分割为若干子图像,最后在充分考虑全局以及各子图像的边缘梯度信息后,自适应地生成动态阈值。(The new Canny adaptive method divides image into sub-images,then determinates the thresholds automatically according to the whole image edge information and the sub-images edge information.)
