摘要： Method and apparatus for intra prediction mode coding and decoding are disclosed. In one embodiment, the encoding and decoding process assigns individual indices and codewords to DC mode and Planar mode respectively. The flag is set if the current intra prediction mode is equal to any of one or more neighboring intra prediction modes. Variable length codes are designed for a remaining mode set. If the flag is not set, the currently intra prediction mode is encoded using the variable length codes. In another embodiment, multiple most probable modes are used. If the current intra prediction mode is not equal to any of the multiple most probable modes, the current intra prediction mode is encoded using variable length codes designed for the corresponding remaining modes according the ranking order of the remaining modes.

摘要： A method and apparatus for clipping a transform coefficient are disclosed. Embodiments according to the present invention avoid overflow of the quantized transform coefficient by clipping the quantization level adaptively after quantization. In one embodiment, the method comprises generating the quantization level for the transform coefficient of a transform unit by quantizing the transform coefficient according to a quantization matrix and quantization parameter. The clipping condition is determined and the quantization level is clipped according to the clipping condition to generate a clipping-processed quantization level. The clipping condition includes a null clipping condition. The quantization level is clipped to fixed-range represented in n bits for the null clipping condition, where n correspond to 8, 16, or 32. The quantization level may also be clipped within a range from −m to m−1 for the null clipping condition, where m may correspond to 128, 32768, or 2147483648.

摘要： A novel femtosecond laser nano-ablation technique called Plasmonic Laser Nano-Ablation (PLN). The technique takes advantage of surface-enhanced plasmonic scattering of ultrashort laser pulses by nanoparticles to vaporize sub-cellular structures in attoliter volumes. The use of nanoparticles may overcome problems associated with current FLMS techniques and does not rely on heating for nanodisruption. In PLN, the particle acts as a “nano-lens,” restricting laser light to the near-field of the particle, and only photodisrupting structures that are nanometers away. This eliminates the need for a tightly focused beam, while still achieving nanoscale ablation resolution. Moreover, the enhanced scattering around the particles reduces the amount of required laser fluence. A method is provided comprising positioning a nanoparticle in proximity to a surface of a material; irradiating the nanoparticle with a laser tuned close to the nanoparticle's plasmonic frequency; and allowing a near-field effect from the irradiated nanoparticle to photodamage the material.
