This blog post introduces GRLAA (GRadient Line Anti-Aliasing), a relatively simple and efficient method designed to cope with aliased lines, which can often crop up in automotive navigation applications. In the discipline of signal processing, there is a specific sampling frequency called the Nyquist frequency. When sampling a signal at a frequency lower than the Nyquist frequency, the signal reconstructed … Continued

This week at the Embedded Vision Summit in California we are showcasing our latest Convolutional Neural Network (CNN) object recognition demo. Since launching the original demo at last year’s EVS, the demo has been expanded to include multiple network models and is now implemented using Imagination’s own graph compilation library – IMG DNN. What are CNNs? Before continuing, a quick … Continued

360° VR panorama videos have been trending on YouTube since the viewing feature was introduced in 2015. Even without a VR headset they offer a uniquely immersive experience. What I’m referring to are mostly live action movies shot with a growing list of 360° video capable cameras. These panoramas are actually two 360×180 equirectangular 2D images stitched together and projected … Continued

Last year we debuted a collection of PowerVR ray tracing demos designed to improve significantly the aesthetics of real-time and offline rendering. One particularly exciting use case is the interactive lightmapping feature embedded inside the soon to be released update to Unity 5. Even though Imagination is primarily known for the hardware GPU IP we license to silicon vendors, we embraced Unity’s write once, … Continued

The title of this post uses the word ‘revelation’ instead of ‘revolution’ because mobile game engines are only inching their way toward using full-on ray tracing. The mobile game community wants ray tracing but the roadblock has been the lack of hardware fast enough to keep up with the challenging frame rates. This is where Imagination’s optimised for mobile, PowerVR … Continued
