[December Python Pune meetup 2015](http://www.meetup.com/PythonPune/events/227265006/) was held at [Castalia Labs, Pune (India)](http://castalialabs.com/) on 19th Dec, 2015.

It was a full day workshop on Computer Vision - Playing with Camera and Images using Python.

Around 15-20 people attended this meetup.

The workshop was divided into small topics followed by a series of small tasks.

Before the start of the workshop, the following packages needs to be installed:

* opencv

* numpy

* matplotlib

* ipython

* mpldatacursor

Finally, [Jemshid](https://twitter.com/KakeJemshid) started the workshop with the introduction of Opencv and explained:

* Read a photo from webcam and display it.

* Read an image in terms of pixels stored as a multi-dimensional numpy array.

* Understand the boolean logic over numpy array.

* Filtering the pixels by using RGB values.

* Filtering a particular object through grayscaling the images.

* Continuously capturing images and filtering them according to static filter applied and displaying it using matplotlib.

* Difference between Computer Vision and Image processing

Below is the list of tasks we performed:

* Read a photo from webcam and display it.

* Segment out green pixels from a yellow color.

* Filter ball only.

* See the captured result in a loop

At the end of the workshop, we have a general discussions around Open Source Python Projects and about upcoming meetups.
