Neural Network Based Clothing Style Analysis via Deep Filter Bank

Abstract: A neural network based clothing style analysis method is proposed via deep filter bank in this paper. Clothing styles are complicated and high-level concept. We propose to construct the deep filter bank by combining Convolution Neural Network(CNN) with Fisher Vector(FV). Then, the extracted features from the body part are used to train the Part-CNN (p-CNN) model. Multiple p-CNNs are integrated along with the whole body model to train the Clothing Style Analysis Neural Network (CSANN). Experimental results on several benchmark datasets show that the superior performance of the proposed method.

A simple method for designing 2d

Abstract: Two dimensional (2D) nonseparable filter banks with linear phase (LP) are desired for image sub-band coding and compression. In this paper, we propose a method for designing 2D nonseparable filter banks with the LP and near perfect reconstruction (near-PR) properties. By combining the unimodular transformation and a separable |M|-channel LP filter bank, the design problem is simplified to that of two one-dimensional (1D) LP filter banks. For 1D case, a novel method by employing partial cosine modulation is used to design near-PR filter banks with LP analysis and synthesis filters. For 2D case, we cascade two 1D near-PR LP filter banks in the form of tree structure to design a separable LP filter bank. With the unimodular transformation, a nonseparable LP filter bank is obtained. In addition, the filter bank achieves the near-PR property without sophisticated nonlinear optimization procedures. Design example shows the efficiency and simplicity of the proposed method.

Fbmc transmission and reception with increased system spectral efficiency

Abstract: A transmission apparatus (30) serves the purpose of generating a filter bank multicarrier FBMC signal (32) from a payload signal (31). The transmission apparatus (30) comprises an offset quadrature amplitude modulator (41) and a quadrature amplitude modulator (42). The transmission apparatus (30) is adapted to generate at least one resource block from a time-frequency resource grid corresponding to the payload signal (31), wherein each resource block is a specific spectral section for a specific time slot, and comprises one spectral mid-section and at least one spectral border-section being located at a spectral boarder of each resource block. The offset quadrature amplitude modulator (41) is adapted to generate the spectral mid-sections of each resource block by performing an offset quadrature amplitude modulation to a first part of the payload signal (31). The quadrature amplitude modulator (42) is adapted to generate the at least one spectral border section of each resource block by performing a quadrature amplitude modulation to a second part of the payload signal (31).
