| 1 | 2013-07-09 | Digital holography for quantitative phase-contrast imaging | Nitin | ||
| The paper provides simultaneously an amplitude-contrast image and a quantitative phase-contrast image. The technique uses a CCD camera for recording of a Fresnel off-axis hologram and a numerical method for hologram reconstruction. | |||||
| 2 | 2013- 07-16 | A new (semantic) reflexive brain–computer interface: In search for a suitable classifier | Younghak | PPT | |
| The goal of the current study is to find a suitable classifier for electroencephalogram (EEG) data derived from a new learning paradigm which aims at communication in paralysis. A reflexive semantic classical (Pavlovian) conditioning paradigm is explored as an alternative to the operant learning paradigms, currently used in most brain–computer interfaces (BCIs). | |||||
| 3 | 2013-07-23 | Conditions for practicing compressive Fresnel Holography | Sagnjun | ppt | |
| Recently, compressive sensing based on Fresnel wave propagation and sparsity is sued for promoting imaging reconstruction from a hologram. In this talk, we aim to understand the theoretical bounds on the performance of compressive imaging system based on Fresnel wave propagation. | |||||
| 4 | 2013-07-30 | Random-Frequency SAR Imaging Based on Compressed Sensing | Jin-Taek | ||
| In this paper, a random-frequency SAR imaging scheme based on compressed sensing is proposed. If the targets are sparse or compressible, it is sufficient to transmit only a small number of random frequencies to reconstruct the image of the targets. This means that the limitations of the stepped-frequency technique for SAR can be overcome. The available imaging range width can be enlarged significantly, while the range and azimuth resolutions are both maintained. |
