DIY Thermal Imager Uses DIY Gaussian Blur

Arthur T Knackerbracket has found the following story:

Under the right circumstances, Gaussian blurring can make an image seem more clearly defined. [DZL] demonstrates exactly this with a lightweight and compact Gaussian interpolation routine to make the low-resolution thermal sensor data display much better on a small OLED.

[...] used an MLX90640 sensor to create a DIY thermal imager with a small OLED display, but since the sensor is relatively low-resolution at 32×24, displaying the data directly looks awfully blocky. Gaussian interpolation to improve the display looks really good, but it turns out that the full Gaussian interpolation isn’t a trivial calculation write on your own. Since [DZL] wanted to implement it on a microcontroller, the lightweight implementation was born. The project page walks through the details of Gaussian interpolation and how some effective shortcuts were made, so be sure to give it a look.

  Now reread my post for comprehension this time.

    Depends if you want to come over as someone who reads something, misunderstands it, blurts out irrelevant nonsense, and then can't be bothered to correct himself when it's pointed out to him that he erred. Your choice.

      Your choice.

      Indeed.
      I think I'm gonna go to sleep before it gets tomorrow around 'ere.
