Stability

Platform

• FX OS camera: / CTai
  • Bug 965425 - [Madai][Camera][Gecko] Expose ISO settings
    • Analysis: The proposal design in this bug will cause build-break in non-qualcomm platform. Left some comments for heads-up.

• JPEG decoder/encoder improvement: / CTai
  • Bug 968707 - Cavas.ToBlob is slow on B2G
    • Analysis: Looks like OpenMax solution is not workable. I am going to check the multi-thread SIMD/OpenCL solution.

Study

• Image Processing Theory Study / CTai
  • Digital Image Processing, 3/e
    • Build up the domain knowledge of image processing for JPEG encoding and decoding improvement.
