• Market survey:
  • The mobile market seems to shifting towards multicore processors. At CES 2011, at least two companies showcased their new mobile phones (LG Optimus 2X and Motorola ATRIX 4G) based on the NVIDIA Tegra 2 dual-core ARM Cortex A9 processor. This looks promising as it may enable smoother graphics capabilities and may be useful for fast view synthesis on the mobile device. However, some evaluation of power consumption needs to be performed. The chip also includes an ultra-low power (ULP) GeForce GPU and is capable of decoding 1080p HD video. Demo Video
  • Tablets emerging in the market nowadays are using the Tegra 2 processor (e.g. Dell Streak 7 and Motorola XOOM)
  • Qualcomm Snapdragon, Samsung Orion (Video), and Texas Instruments OMAP4 are all dual-core processors expected in the first half of 2011.
  • Slides leaked this weekend from NVIDIA's presentation at the Mobile World Congress indicate that the company will be shipping a Tegra 2 3D processor this year intended for use in mobile gadgets featuring a 3D screen! Although this is yet to be confirmed, it is expected that devices such as LG's G-Slate which is expected to have a glasses-free, three-dimensional display and will be shipping around the same time will run on this processor. Moreover, an announcement of a Tegra 3 processor is expected in February.
  • The recent release of Gingerbread (Android 2.3) has witnessed a concurrent release of a new NDKr5 which allows application lifecycle management and window management to be performed outside Java. This means an application can be written entirely in C/C++/ARM assembly code without need to develop Java or JNI bindings.

• Concentrating on view synthesis in 3D video systems and read two recent survey papers about the topic.
• Reading about multiple view geometry to understand the warping process and the related terms from epipolar, trifocal, and projective geometry.
• Understanding the commonly used camera pinhole model.
• Reading about stereo-based view synthesis.
• Went over 3 papers on real-time view synthesis using GPUs.
