Recreating pixilated images




Pixilated images are images that have been zoomed to a point that the picture is no longer clear and one can’t tell what the image is about. 

Most science fiction movies use this their scene. In their control room they get a satellite image of an individual and display it in a big screen but usually not clear and there is this IT geek with glasses keys in a few keys on the keyboard and walla a clear image of the individual is seem.

Goggle has now brought these to reality. By the use of deep machine learning project Google brain software is able to analyze the pixilated image and be able to recreate a better image that will be easy to use.

Google Brain's software does this with two stages of neural network training. The first stage involves a "conditioning network" that cross references the 8 x 8 pixelated image with similar-looking images that are higher resolution and then downsized, checking for patterns and colors

The second stage, called the "prior network" then uses details from high-resolution images to try to fill out the low-resolution images.

"When some details do not exist in the source image, the challenge lies not only in ‘deblurring’ an image, but also in generating new image details that appear plausible to a human observer," the Google Brain researchers wrote in their paper.

They have carried out successful test with celebrities photos which they pixilated then fed the machine to observe how it will recreate it.  Its still not yet clear when the full product will be out or even if it will be commercialized

As technologies professionals this might end up as a good innovation in the security field as video output from DVR with very poor quality which end up not valuable  because in the event of crime the criminals is not visible.With these innovation will come in handy in recreating the images .

Revolutionizing Agriculture: Precision Farming with Drones and Sensors

  Drones in Agricuture In the rapidly evolving world of agriculture, precision farming stands out as a groundbreaking approach that harnesses the power of technology to enhance productivity, sustainability, and efficiency. Among the most transformative tools in this field are drones and sensors, which are redefining traditional farming practices. This article delves into how these technologies are being integrated into modern agriculture, the benefits they offer, and the future they promise. The Rise of Precision Farming Precision farming, also known as precision agriculture, involves the use of technology to manage crops and soil in a more precise and controlled manner. The goal is to optimize field-level management regarding crop farming. Unlike conventional methods that rely on broad-spectrum approaches, precision farming tailors practices to the specific needs of different areas within a field. Drones: Eyes in the Sky Drones, or unmanned aerial vehicles (UAVs), have become an i...

Early Detection of Brain Disorders: Using Wearable Devices Through Eye Movement

 Early Detection of Brain Disorders Using Wearable Devices Through Eye Movement Introduction In recent years, the integration of wearable technologies into healthcare has opened up exciting possibilities for early disease detection. Among these developments, wearable sensors that track eye movement have emerged as a promising tool in diagnosing brain disorders. Eye movement, which is closely linked to brain function, can offer vital clues in detecting neurological conditions such as Parkinson’s disease, Alzheimer’s, and other cognitive impairments. This research addresses a pressing question: Can subtle changes in eye movement patterns be reliably used to detect brain disorders before clinical symptoms become evident? With advancements in precision medicine and AI, the convergence of IT, biomedical engineering, and neuroscience is becoming not only possible but necessary. As a software engineer transitioning into bioinformatics, I see this as a pivotal opportunity to apply data sc...
