Amplitude reconstruction of clipped OFDM by using DFT-based least squares (Sharif University of Technology, 2017-06-01)OFDM is an e ective multicarrier transmission technique with one primary disadvantage; it su ers from high Peak-to-Average Power Ratio (PAPR). Although clipping and ltering is a simple and e ective method for PAPR reduction, ...

DiReT: An effective discriminative dimensionality reduction approach for multi-source transfer learning (Sharif University of Technology, 2017-06-01)Transfer learning is a well-known solution to the problem of domain shift in which source domain (training set) and target domain (test set) are drawn from di fferent distributions. In the absence of domain shift, ...

Effiiently computing the smallest axis-parallel squares spanning all colors (Sharif University of Technology, 2017-06-01)For a set of colored points, a region is called color-spanning if it contains at least one point of each color. In this paper, we rst consider the problem of maintaining the smallest color-spanning interval for a set of ...

Recognizing traffic signs using flexible Discrete Cosine Transform (DCT) grid (Sharif University of Technology, 2017-06-01)Tra ffic sign recognition can be performed in two phases of detection and recognition; detection deals with sensing a tra c sign in real-world image or video frame while recognition is about reading its contents. A traffi ...

Repeating average filter for noisy texture classification (Sharif University of Technology, 2017-06-01)In this paper, it is shown that repeating average lter increases the uniform patterns of noisy textures and, consequently, increases the classi cation accuracy of textures. In other words, for noisy textures, rst, an ...
