NVIDIA has long been known for its immaculate Graphics Processing Units (GPUs), its main product being the NVIDIA GeForce card. With that, the company has always been front and center in the research and development of experience enhancing artificial intelligence in video games, graphic design, data processing, and automotive vehicles.
Lately, NVIDIA has started focusing on artificial intelligence in isolation with its most recent project taking a heavy focusing on the smart reimaging of preexisting photos using gaussian algorithms to evaluate the loci least differences between hundreds of clear and blurry images categorized based upon temperature and tint, and then inputting those values into the regression expressions of individual blurry photos to regress back to what their original clear images could have looked like. This process is carried out individually for every point on the photograph and a summation is used to generate a generic least difference value.
The algorithm works to learn from past attempts of what certain colors and patterns on screen indicate. When the system was developed, it was thousands of made-blurry and original images so that the machine could identify which patterns and colors on the screen correspond to which grooves and edges in the original image. Having been tested many times, NVIDIA has managed to teach its AI chip to learn from previous trials and store a database of matched graphic codes that are converted into mathematical code based upon location, tint, and temperature. Using past experience and the relationships established between the blurry and clear images of the same locus and tint, the machine cracks on with new images, applying the formulae that match the new photo’s tint and temperature best. NVIDIA has put their algorithm through enough trials to have a strong enough retention database that the AI can tap into when working on newer images and the mechanism now stands on its own, able to uncover virtually any image by its training in reinforcement learning (RL). After uncovering enough faces, for example, the machine can make out blurry faces when put to the test as it understands which blurry grooves correspond to which facial features in truth. Exposure to different kinds of noise such as overstretched, whitewashed, filtered, and textured images has added to the algorithms database as well.
In the algorithm’s mathematical language, the program reads corresponding corrupted and clear loci on corresponding images, logging x, y, x’, and y’ into its database. It then creates a gaussian regression curve to match the differences between the two which allow for conversion based upon general photographic noise. In the least squares regression expression generated, the lowest value that satisfies the condition is taken and a new curve of the gaussian value is plotted. When converting the image back to its original clear quality, every point’s temperature is changed based upon the difference of the regression pattern in the AI machine’s database that corresponds to that particular color and pattern and each point is turned over to produce a whole clear image. The gaussian curving mechanism factors in the most generic forms of noise but if the device is able to identify other forms of noise that are often attributed to ill-timed shutter speeds or generic shading of the immage, the gaussian least difference value is averaged with the data set’s poisson (for the former) and Bernoulli (for the latter) least difference values as well.
In laymen’s terms, the role that artificial intelligence plays in this is the smart detection and conversion of unique photos based upon a practice set already attempted by the device. When it comes to the level of artificial intelligence achieved today, which is still at a stage where it is not particularly independent and has its efforts limited to the range of scenarios already practiced, NVIDIA has achieved greatly in creating a machine that can attempt and recreate unseen photos with the highest level of accuracy by consistently adapting and expanding its database to improve the success rate of subsequent photographic turnovers.
