پردازش تصویر در سیستم‌های نهفته نوین با استفاده از بسترهای نرم‌افزاری آزاد

119 views

Published on

بینایی ماشین و پردازش تصویر از بحث‌های مهم در حوزه علوم کامپیوتر است و به دلیل محاسبات سنگین، نیازمند سخت‌افزار قدرتمند است. امروزه با پیشرفت قابل ملاحظه در توان پردازشی سیستم‌های نهفته (Embedded Systems)، امکان پیاده‌سازی الگوریتم‌های محاسباتی در دستگاه‌های مستقل کوچک فراهم آمده است. منتها پیاده‌سازی این حجم از محاسبات در این سیستم‌ها بدون استفاده از سیستم عامل میسر نیست. پیدایش سیستم‌های عامل آزاد و همچنین کتابخانه‌های متعدد متن‌باز و آزاد، در تکامل این روند بسیار مؤثر بوده است. هدف از برگزاری این کارگاه، آشنایی شرکت‌کنندگان با تعدادی از قویترین بسترهای آزاد موجود جهت استفاده در سیستم‌های نهفته می‌باشد.

سرفصل‌ها:

معرفی مفاهیم بینایی ماشین و پردازش تصویر
معرفی کتابخانه‌های نرم‌افزاری آزاد برای پردازش تصویر
معرفی و انجام یک پروژه ساده با استفاده از پایتون و بستر آزاد OpenCV

  1. 1. Embedded Systems Image Processing using Free Software Platforms Abolfazl Danayi adanayi95@gmail.com Software Freedom Day Sharif University of Technology 29th September 2016 Abolfazl Danayi 9/29/2016 Embedded Systems 1 / 9
  2. 2. Outline • Computer Vision and Image Processing Definitions • Usage of Embedded Systems (and OS) in Applications • Some Intensive Computation Capable SoC Devices • Free computer Vision Platforms • Implementing An Offline Image Processing Example Application • Implementing A Real-Time Computer Vision Example Application Abolfazl Danayi 9/29/2016 Embedded Systems 2 / 9
  3. 3. Image Processing and Computer Vision definition Image Processing What is Image Processing? The analysis and manipulation of a digitized image, especially in order to improve its quality. Computer Vision What is Computer Vision? Computer vision is the science that aims to give a similar, if not better, capability to a machine or computer. Computer vision is concerned with the automatic extraction, analysis and UNDERSTANDING of useful information from a single image or a sequence of images. Abolfazl Danayi 9/29/2016 Embedded Systems 3 / 9
  4. 4. IP and CV: The main applications IP and CV typical applications: • Image enhancement • Classification and Pattern-Rocognition • Feature extraction • Multi-scale signal analysis • Projection (3D) Abolfazl Danayi 9/29/2016 Embedded Systems 4 / 9
  5. 5. Why Embedded Systems? Image Processing needs computation • An image is a Matrix set • Image feature extraction needs lots of calculations • This amount of processing needs to be managed. • Both supervised and unsupervised machine learning NN algorithms need a lot of computation. It is not just about processing! There are some other tasks: • Image acquisition • Image files, results and ... should be saved • Monitoring upon system tasks • Result/Image transportation • Video output Abolfazl Danayi 9/29/2016 Embedded Systems 5 / 9
  6. 6. Why Embedded Systems? Image processing is not only Image enhancement • Image enhancement is more about calculations... • But IP is not just IE!!! :— • An FPGA or any other HDL inscribed device can handle parallel processing, even REAL-TIME ones!. • But what about some other tasks, like Unsupervised CLASSIFICATION?

  7. 7. Why Embedded Systems? Embedded Systems as a solution -Using of Embedded systems is not the only way. -Advantages of having OS Abolfazl Danayi 9/29/2016 Embedded Systems 7 / 9
  8. 8. How to use an embedded system? Linux based devices: -RPi family, based on ARM Cortex-A Broad-com ICs -Intel Family SoC devices: Intel Joule, Galileo and Edison -Beagle Bone Black Windows 10 IoT core based devices: -RPi on the top: ;) Abolfazl Danayi 9/29/2016 Embedded Systems 8 / 9
