This post will cover some use cases of the ESP-32 Cam module in low or no light conditions. The software and hardware of the ESP-32 Cam module will modified for this purpose. Some additional hardware examples will be introduced as well. Lastly, the use of FFMpeg will be demonstrated to further enhance the images gathered from the ESP-32 cam module. What are some reasons for the ESP-32 Cam module to be used in low or no light environments? The more…
I had written a post awhile back about color isolation using imagemagick. Here is a recap, but this time using FFMpeg. This turned out to be a good color pattern to do testing against. the reason I prefer this is because it contains white and black space to visually understand the results of the filter. Lets try this command. ffplay -i “color-pattern.jpg” -vf “colorhold=0xFF0000:similarity=0.25” Now our image shows only the defined color threshold, in this example it’s red. Here are…
In this post I’ll demonstrate how to stabilize and enhance low resolution video using FFMpeg. I will also discuss the pros and cons of hardware options available. From there the discussion will show examples of software options that have supplanted hardware. Lastly, I will introduce some examples of AI that others have used. The Z51 660mm Below is a side by side comparison of video taken from one of my fixed wing remote control (RC) planes. Here is the script…
