A Novel Joint Data-Hiding and Compression Scheme Based on SMVQ and Image Inpainting Abstract?A Novel Joint Data-Hiding and Compression Scheme Based on SMVQ and Image Inpainting. In this paper, we propose a novel joint data-hiding and compression scheme for digital images using side match vector quantization (SMVQ) and image inpainting. The two functions of data…
1.2 V 10-bit 75 MS/s Pipelined ADC With Phase-Dependent Gain-Transition CDS Abstract?A phase-dependent gain-transition correlated double-sampling technique is proposed and applied to a 10-bit 75-MS/s pipelined analog-to-digital converter.< Final Year Projects > This reduces the accumulation of predictive error of each multiplying digital-to-analog converter stage due to the finite gain of the operational amplifiers, without…
2.5 GB/s hybrid WDM/TDM PON using radio over ?ber technique Abstract? 2.5 GB/s hybrid WDM/TDM PON using radio over ?ber technique. Hybrid gigabit-passive optical network (GPON) is a hybrid passive optical network, where wavelength division multiplexing (WDM) GPON and time division multiplexing (TDM)-GPON are integrated into a single passive optical network, reducing cost and increasing…
3-D Adaptive Sparsity Based Image Compression With Applications to Optical Coherence Tomography Abstract? We present a novel general-purpose compression method for tomographic images, termed 3D adaptive sparse representation based compression (3D-ASRC). We focus on applications of 3D-ASRC for the compression of ophthalmic 3D optical coherence tomography (OCT) images. The 3D-ASRC algorithm exploits correlations among adjacent…
3-D Face Recognition Under Occlusion Using Masked Projection Abstract?With advances in sensor technology, the three-dimensional (3-D) face has become an emerging biometric modality, preferred especially in high security applications. However, dealing with occlusions covering the facial surface is a great challenge, which should be handled to enable applicability to fully automatic security systems. In this…
3D Brain Atlas Reconstruction Using Deformable Medical Image Registration: Application to Deep Brain Stimulation Surgery Abstract?In deep brain stimulation surgery the most important step is the correct location of the neurostimulator device. Here, the medical specialist needs to robustly locate the basal ganglia area (i.e. subthalamic nucleus) to implant the neurostimulator. 3D brain atlas reconstruction…
A 16 Kb Spin-Transfer Torque Random Access Memory With Self-Enable Switching and Precharge Sensing Schemes Abstract?Spin-transfer torque magnetic random access memory (STT-MRAM) is considered one of the most promising non-volatile memory candidates thanks to its excellent performance in terms of access speed, endurance, and compatibility to CMOS. However, high power supply voltage is required in…

A Balanced-to-Unbalanced Microstrip Power Divider With Filtering Function Abstract? A balanced-to-unbalanced microstrip power divider based on branch lines with several stubs and one resistor is proposed. The functions of power dividing, frequency selectivity, isolation between output ports, and common-mode suppression can be realized at the same time. The even?odd-mode equivalent circuits combining with the standard…
A Bayesian Bounded Asymmetric Mixture Model With Segmentation Application Abstract? Segmentation of a medical image based on the modeling and estimation of the tissue intensity probability density functions via a Gaussian mixture model has recently received great attention. However, the Gaussian distribution is unbounded and symmetrical around its mean. This study presents a new bounded…
A Bidirectional Three-level LLC Resonant Converter with PWAM Control Abstract? A bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation < PWAM > control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it can achieve wide voltage gain range by switching among these…
A Block-Mean Difference Based Sorting Scheme on Lossy Partail Distortion Search for Fast Optimal Motion Estimation Abstract? This work presents an efficient lossy partial distortion search (PDS) algorithm named adaptive mean difference based partial distortion search (A-MDPDS). The proposed A-MDPDS algorithm reduces computations by using a halfway-stop technique in the calculation of block distortion measure…
