对图像的去噪处理，包括了加权梯度领域去噪、高斯模板去噪和两种方法的结合(Denoising of images, including the weighted gradient field denoising, Gaussian model for denoising and the combination of two methods)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

retina segmentation using morphology

this is a importance document

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding the SNR to see how well decompression works

river formation dynamics algorithm implementation in matlab

this octave exercise you will rst implement the k-means and GMM (Gaussian Mixture Model) clustering algorithms. Then you will create a BOW (Bag of Words) representation of sample images and use it to recognize object classes in these images
