Overview

Welcome to the software wiki of "Eyes of Things", an international project focused on building an open embedded computer vision platform. See more information about EoT in the website.

After more than a year of development we are gradually migrating to this public repository. Expect more software in the upcoming weeks. We are doing likewise with the hardware boards.

The repository is essentially organized according to platform. 'Myriad' is the platform used by EoT. There are also folders for Android and desktop platforms.

Unless stated otherwise, this code is released under the MIT License.

We encourage you to contribute (e.g. new features, bug fixes, a great idea, etc.) to the project. All contributions are welcome and greatly appreciated!

Myriad

Libraries

OpenCV

OpenCV is a widely-used computer vision library with thousands of functions. OpenCV 1.0 has been ported to the EoT board. Additionally, functionality has been added so that later OpenCV versions can be executed in an external server.

libccv

libccv is a minimalist open-source computer vision library for embedded devices. It has been ported to the EoT board with some limitations.

Read more

Quirc

Quirc is a library for extracting and decoding QR codes from images. It is fast enough to be used with real time video.

Read more

Crypto

Crypto is a library for file system encryption. It uses the symmetric key block cipher algorithm "Advanced Encryption Standard" (AES) with the Counter Mode (CTR) in order to provide data confidentiality.

It is used in:

• OpenCV Examples
• libccv Examples

SDCardIO

SDCardIO is a library for file system management. It is use to develop applications that interact with a Secure Digital Card (SDCard).

Read more

cblas

cblas is a combination of CBLAS and CLAPACK libraries adapted to Myriad 2.

It is used in:

• libccv

Read more on cblas/README.md

embUnit

Embedded Unit is unit testing framework for Embedded C System.

It is used in:

• crypto unittests
• sdcard unittests

Read more on embUnit/readme_en.txt

libpng

libpng is the official PNG reference library adapted to Myriad 2. It supports almost all PNG features, is extensible, and has been extensively tested for over 20 years.

It is used in:

• OpenCV
• libccv
• Quirc examples

Read more on libpng/README.md

zlib

zlib is a general purpose data compression library adapted to Myriad 2. All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952.

It is used in:

• OpenCV
• libccv
• libpng

Read more on zlib/README.md

Audio

Audio library provides functions for playing and recording audio in the Myriad 2.

Read more

HistogramMatching

HistogramMatching library provides functions to:

• Convert images into different colour spaces.
• Compute colour histograms.
• Compute histogram matching scores.

Read more

timeFunctions

timeFunctions library provides common time functions.

ElfLoader

ElfLoader library provides functionality to load ELF files from the flash into the memory (ELF files are the binary application files).

FlashIO

FlashIO library provides functions for read/write file from/to the Flash-EEPROM. It provides a minimal filesystem for the flash memory to manage the placement and retrieval of the individual applications (bootloader, control mode and user apps) in the flash memory.

WifiFunctions

WiFiFunctions library provides common wifi functions such as handling WLAN events, generating an Acces Point or changing the operation mode of the device.
