Fuzzyclustering
模糊聚类;涉及事物之间的模糊界限时按一定要求对事物进行分类的数学方法。聚类分析是数理统计中的一种多元分析方法,它是用数学方法定量地确定样本的亲疏关系,从而客观地划分类型。事物之间的界限,有些是确切的,有些则是模糊的。例如人群中的面貌相像程度之间的界限是模糊的,天气阴、晴之间的界限也是模糊的。当聚类涉及事物之间的模糊界限时,需运用模糊聚类分析方法。模糊聚类分析广泛应用在气象预报、地质、农业、林业等方面。通常把被聚类的事物称为样本,将被聚类的一组事物称为样本集。模糊聚类分析有两种基本方法:系统聚类法和逐步聚类法。

小波变换的图像压缩 jpeg2000_matlab
JPEG 2000是基于小波变换的图像压缩标准,由Joint Photographic Experts Group组织创建和维护。JPEG 2000通常被认为是未来取代JPEG(基于离散余弦变换)的下一代图像压缩标准。JPEG 2000文件的副档名通常为.jp2,MIME类型是image/jp2。 JPEG 2000的压缩比更高,而且不会产生原先的基于离散余弦变换的JPEG标准产生的块状模糊瑕疵。JPEG 2000同时支持有损数据压缩和无损数据压缩。另外,JPEG 2000也支持更复杂的渐进式显示和下载。 JPEG 2000是国际标准化组织(ISO)发布的标准,文档代码为ISO/IEC 15444-1:2000。虽然JPEG 2000在技术上有一定的优势,但是到目前为止(2006年),互联网上采用JPEG 2000技术制作的图像文件数量仍然很少,并且大多数的浏览器仍然不支持JPEG 2000图像文件的显示。但是,由于JPEG 2000在无损压缩下仍然能有比较好的压缩率,所以JPEG 2000在图像品质要求比较高的医学图像的分析和处理中已经有了一定程度的广泛应用。

LeastSquare
this is matlab code for estimating the static linear system with Least Squre that is written by matlab 7.0.
Here we want to estimate the below function:
1 - u^2 + 2*u^3 +u^5 +3*u^7
these are 2 files : without noise and with noise
finally,there are plots for showing results.

1. Comenzar con un punto arbitrario
2. Calcular Gradiente de Fi
3. Si el Gradiente Fi es igual a 0(converge), termina
4. Si el Gradiente Fi es !=0 continuar
5. Encontrar dirección de búsqueda
Si= -GradienteFi= - Gradiente F(Xi)
6. Determinar la Longitud Optima del incremento lamda(i) en dirección Si
X(i+1)=X(i)+lamda(i)*S(i)= X(i)-lamda(i)*Gradiente F(Xi)
7. Hacer i=2
8. Obtener Gradiente Fi
9. Calcular Si= -GradFi + ( [abs(GradFi)^2]/[abs(GradF(i-1))^2] )*S(i-1)
10. Determinar la Longitud Optima del incremento lamda(i) en dirección Si
X(i+1)=X(i)+lamda(i)*S(i)= X(i)-lamda(i)*Gradiente F(Xi)
7. Verificar Optimalidad de X(i+1)
Si es optimo, detener
Si no es optimo hacer i=i+1 e ir al paso 8
