Image Processing – Python and OpenCV – Capture Image From Webcam
by Jamie Starling | July 21, 2022 | The Art of Technology | 0 Comments
Let's take a quick look on how we can use OpenCV2 to capture a single frame from a webcam. The code below uses a web cam to capture a single frame, that stores the results in the image variable. We are using direct show to communicate with the cam and adjust the...

The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975. The Zilog Z80 is a software-compatible extension and...
Image Processing – Python and OpenCV – Convert Image to Gray Scale
by Jamie Starling | June 17, 2022 | The Art of Technology | 0 Comments
In the past posts we looked at doing some image conversions using arrays and manual steps. All that is fun, it lets us see what is going on inside the black box. However, deadlines and everything else - we don't want to have to reinvent the wheel each time. Thankfully...
Image Processing – Python Generating a Histogram for a Gray Scale Image
by Jamie Starling | June 15, 2022 | The Art of Technology | 0 Comments
What is an image histogram - it is a profile of the occurrences of each gray level present in an image. In the visual example below - we are using a bar graph to visualize it. It starts at 0 and goes to 255, each vertical bar represents the number of times the...
Image Processing – Python Convert Image to Gray Scale – Single Color Channel
by Jamie Starling | June 8, 2022 | The Art of Technology | 0 Comments
In the last post we took a look at averaging the RGB channels to produce a gray scale image. It does require some math division to get the result. If you need a way that is even simpler and faster than averaging - we can extract the values from one of the color...
Image Processing – Python Convert Image to Gray Scale – Average
by Jamie Starling | June 8, 2022 | The Art of Technology | 0 Comments
Let's us look at some ways of converting a color image into a black and white or gray scale image. The most straight forward approach is averaging the three color channels, RGB. GrayValue = (Red + Green + Blue) / 3 You do this for every pixel. It is quick and dirty....

There are a tons of image already - instead of going though the pain staking process of creating by hand our own images, I am going to use an image I already captured. And yes, it is of my three cats. I am also adding to the collection of cat images on the internet....
Image Processing – Color Image Arrays
by Jamie Starling | June 6, 2022 | The Art of Technology | 0 Comments
Up to this point we have been dealing with Black and White images or Gray Scale images - that can be represented by a 2d array. Array(height, width) In which each element in the array represents one pixel and the level of gray, with 0 being black and 255 being white....
Image Processing – Memory Usage
by Jamie Starling | June 2, 2022 | The Art of Technology | 0 Comments
Something to consider is the memory usage for the images that you will be processing. Given a 100x200 image - black and white. That 100x200 array takes up roughly 20K of ram. If it is a color image, it would be 3 times that - because each color channel (RGB) is...

by Jamie Starling | August 2, 2022 | White Rabbit | 0 Comments
{This is a post a did a few years ago – can apply to other art forms as well. The idea that there is just one way to do something – just because others have been doing it that way. } So, how many times have you heard the line “Get it right in camera.” Every time I see...

Camera As A Receiver For Images
by Jamie Starling | July 22, 2022 | White Rabbit | 0 Comments
I was thinking about this the other day. When we photograph something, we say.. “Capture” “Take” “Create” “Make” .. so on.. This idea came to me, after a discussion on getting vs being open to receive. Here is the idea of getting verses receiving. We often strive to...
