Tcheslavski: gleb@ee.lamar.edu http://ee.lamar.edu/gleb/dip/index.htm Spring 2008 ELEN 4304/5365 DIP 1 Mechanics of spatial filtering Considering frequency domain filtering‚ the effect of LPF applied to an image is to blur (smooth) it. Similar smoothing effect can be achieved by using spatial filters (spatial masks‚ kernels‚ templates‚ or windows). We discussed that a spatial filter consists of a neighborhood and a pre-defined operation

investigate the performance of novel classification schemes for spectrum sensing in cooperative multiple-input multiple-output (MIMO) wireless cognitive radio (CR) networks. In this context‚ we consider several optimal classification schemes such as support vector classifiers (SVC)‚ logistic regression (LR) and quadratic discrimination (QD) for primary user detection. It is demonstrated that these classification techniques have a significantly reduced complexity of implementation in practical CR applications

com Abstract. We present a novel method for generic visual categorization: the problem of identifying the object content of natural images while generalizing across variations inherent to the object class. This bag of keypoints method is based on vector quantization of affine invariant descriptors of image patches. We propose and compare two alternative implementations using different classifiers: Naïve Bayes and SVM. The main advantages of the method are that it is simple‚ computationally efficient

• Na¨ Bayes ive You need to try Naive Bayes without smoothing and use smoothing. • k -Nearest Neighbor for kNN‚ k is a parameter. You need to report two result‚ k =1 and k =p. you can choose an appropriate p for different datasets. • Support Vector Machine Use both LibSVM (http://www.csie.ntu.edu.tw/~cjlin/libsvm/) and LibLinear (http://www.csie.ntu.edu.tw/~cjlin/liblinear/) Use LibSVM with linear kernel and Gaussian Kernel (tune the parameters) LibLinear is always linear‚ you need to compare

We recognize different low-level activities by measuring the user’s continuous weight distribution over the feet with twelve Force Sensing Resistor (FSR) sensors embedded in the insoles of shoes. Using the sensor data as inputs‚ a Support Vector Machine (SVM) classifier identifies up to eighteen mobile activities and a four-directional foot control gesture at approximately 98% accuracy. By understanding user’s present activities and foot gestures‚ this system offers a nonintrusive and always-available

I know if you ever see my books in the hallway they are kind of a mess with papers but I know how to set up conferences‚ make lists‚ and organize events. I also never give up. In anything I do‚ I believe that if you start something you should see it through. One example of this is my calculus class. I started out
