Results Digital Image Processing •  Gray Balance •  Neutral Balance •  White Balance •  K-means algorithm Android SDK •  Eclipse + ADT plugin •  Android SDK Tools •  Android system image emulator App •  Interfaced Camera •  RGB Values + more •  Displays colour names •  Combine versions Initialising representatives (means) Final App Layout Initialise means: •  By picking k samples at random Iterate: •  Assign each point to nearest mean •  Move “mean” to center of its cluster. Conclusion •  A method for detecting colours using a portable device with calibration techniques was achieved. •  Camera interfacing and digital signal processing techniques were applied. •  Furthermore, k-means clustering was computed and incorporated into a mobile device. Features •  Colour detection •  Image calibration •  Identification of RGB values •  Colour storage Android's Camera HAL overview Android's camera Hardware Abstraction Layer (HAL) connects the higher level camera framework APIs in android hardware to a underlying camera driver and hardware. The following figure describes the components involved. Future Work •  Test more algorithms on a mobile device. •  Update colour library. Architecture Summary
