Description: We propose an algorithm for facial expression recognition which can classify the given image into one of the seven basic facial expression categories (happiness, sadness, fear, surprise, anger, disgust and neutral). PCA is used for dimensionality reduction in input data while retaining those characteristics of the data set that contribute most to its variance, by keeping lower-order principal components and ignoring higher-order ones. Such low-order components contain the "most important" aspects of the data. The extracted feature vectors in the reduced space are used to train the supervised Neural Network classifier. This approach results extremely powerful because it does not require the detection of any reference point or node grid. The proposed method is fast and can be used for real-time applications.

Description: Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI, this allows rapid image reconstruction. There are numerous publications on MR gridding reconstruction.
The tar file includes numerous .m scripts, and C code that can be compiled to a .mex function.
You will need to compile the MEX functions - in Matlab try "mex gridlut_mex.c" and "mex calcdcflut_mex.c" These should result in files gridlut_mex.mex??? and calcdcflut_mex.mex??? where ??? depends on your operating system.

Description: 自定义函数画图软件，软件的函数输入部分分为4部分，针对的是4个分段函数，当然也可以扩展为5段，六段，如果你的函数不用分段，那就只用在第一个edit里面写下你的函数表达式即可，同时要在后面写出x的范围，和cftool里面的custom equation一样，只能用matlab语法规范的函数表达式，即你不要写2x而是2*x，不要把我们的数学表达式和matlab表达式搞混淆了。从gif可以看出，在第一个edit输入不同的函数，有多项式函数，指数函数，三角函数，对数函数，axes都能有正确的图形，另外用其他edit配合，画出分段函数图像。因此，这可软件无论你是单个函数还是分段函数（4段以内）均可正确画出，当然还配合有grid选项，如果想保持画出的图形，无需QQ截屏，直接点保存键，将它以jpg的格式，存入到你想要存的文件夹里面。要想查对应点的函数值时，只用在edit里面输入x值，按回车就可以得到，注意x值是在范围之内的，支持结果累积，最终将以一个表格的形式显示出来，如果要想画新的图形，点击清空按键即可。-Drawing software-defined functions, the software function of the input part is divided into 4 parts, for the four sub-functions, of course, can also be extended to 5, Liu Duan, if you do not have sub-function, then only the first an edit which you can write your function expression, while the range in the back to write x, and cftool inside the custom equation, can only function with matlab syntax specification expression, but that you do not write 2x 2* x, not to our matlab mathematical expressions and expressions confused. It can be seen from the gif, in the first edit enter a different function, there polynomial functions, exponential functions, trigonometric functions, logarithmic functions, axes can have the right graphics, the other with the use of other edit, draw piecewise function image. Therefore, it can be software or whether you are single function piecewise functions (4 or less) can be correctly drawn, of course, with a grid option, if you want to keep drawing the graphics, Platform: |

Description: RNA 和 DNA序列模拟 基因建模 数值模拟 采用matlab 编写 能计算几千个 基因点的特性和行为-In one type of gene expression analysis, fluorescently tagged messenger RNA from different cells are hybridized to a microscopic array of thousands of complimentary DNA spots that correspond to different genes. Illuminated spots emit different color light, indicating which genes are expressed (e.g., green=control, red=sample, yellow=both).
In this case study, MATLAB, the Image Processing and Signal Processing toolboxes were used to determine the green intensities from a small portion of a microarray image containing 4,800 spots. A 10x10 pattern of spots was detected by averaging rows and columns to produce horizontal and vertical profiles. Periodicity was determined automatically by autocorrelation and used to form an optimal length filter for morphological background removal. A rectangular grid of bounding boxes was defined. Each spot was individually addressed and segmented by thresholding to form a mask. The mask was used to isolate each spot from surrounding background. Individu Platform: |

- ZI = mirt2D_mexinterp(Z,XI,YI) interpolates 2D image Z at the points with coordinates XI,YI. Z is assumed to be defined at regular spaced points 1:N, 1:M, where [M,N]=size(Z).
If XI,YI values are outside the image boundaries, put NaNs in ZI.
The function is similar to Matlab s native
ZI = INTERP2(Z,XI,YI, linear ,NaN),
but is much master. If Z is vector valued 2D image (3D array), then iteratively interpolates Z(:,:,1), Z(:,:,2),Z(:,:,3),.. etc. This works faster than to interpolate each image independently, such as
ZI(:,:,1) = INTERP2(Z(:,:,1),XI,YI)
ZI(:,:,2) = INTERP2(Z(:,:,2),XI,YI)
ZI(:,:,3) = INTERP2(Z(:,:,3),XI,YI)
The extra speed gain is from the precomputation of coefficients for interpolation, which are the same for all images. Interpolation of a set of images is useful, e.g. for image registration, when one has to interpolate image and its gradients or for vector valued images such as RGB.
Limitations: only works for images on a regular grid, Platform: |

Description: image(C) displays the data in array C as an image. Each element of C specifies the color for one pixel of the image. The resulting image is an m-by-n grid of pixels where m is the number of columns and n is the number of rows in C. The row and column indices of the elements determine the centers of the corresponding pixels.
image(x,y,C) specifies the image location. Use x and y to specify the locations of the corners corresponding to C(1,1) and C(m,n). To specify both corners, set x and y as two-element vectors. To specify the first corner and let image determine the other, set x and y as scalar values. The image is stretched and oriented as applicable. Platform: |
