Face detection and identification using OpenCL on PowerVR GPUs

In previous blog posts, we have demonstrated using neural networks to do things such as object recognition and digit recognition. In this post, we will demonstrate a more practical example of vision, AI and machine learning running on PowerVR GPUs. This demo is showing how we can utilise

Convolutional neural networks in action

These days we seem to take it for granted how powerful and sophisticated computers have become. We can talk to our phones and our Bluetooth speakers and they will respond with context-aware information; in certain cars you can take your hands off the wheel and let yourself be

Object recognition using Convolutional Neural Networks on a PowerVR GPU

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

Showing our vision with OpenVX™ 1.1 support for PowerVR GPUs

You may already have seen that Imagination has announced that its PowerVR GPUs are the first to achieve conformance with the OpenVX 1.1 specification from the Khronos™ Group. OpenVX is an open, royalty-free standard API for cross-platform acceleration of computer vision applications. By being ahead of the game,

Deep learning on mobile devices at the Embedded Vision Summit 2016

It was clear last week at the annual Embedded Vision Summit in Santa Clara that the time of computer vision and deep learning on mobile had finally arrived. Interest in the area is growing noticeably – the Summit program expanded from one to two days this year, there

PowerVR Series7XT Plus GPUs: where advanced graphics meets computer vision

About a month before CES 2015 I wrote an in-depth blog article about our PowerVR Series7XT GPUs, presenting the industry-leading performance efficiency gains made since Series6XT and giving an overview of their desktop-class features. Today I’m very excited to announce GT7200 Plus and GT7400 Plus, two new GPUs

Deep dive: OpenCL face detection on PowerVR [part 3]

Imagination’s R&D group has developed a face detection algorithm, which is based on a classifier cascade and is optimized to run on mobile devices comprising a CPU and PowerVR GPU. The algorithm employs several optimizations to improve performance and accuracy. In particular, instead of searching each entire frame

Deep dive: Hardware IP for computer vision [part 2]

Modern mobile application processors are highly heterogeneous, combing a variety of different hardware components optimized for different tasks. As shown in the figure below, a processor designed for vision might include an Image Signal Processor (ISP) for acquiring image sensor data, a vector processor such as a GPU

Deep dive: Implementing computer vision with PowerVR [part 1]

Computer vision is the use of computers to extract useful meaning from images, such as those that arise from photographs, video and real-time camera feeds. Thanks to the proliferation of low-power parallel processors, the increasing availability of 3D sensors and an active ecosystem of algorithm developers, it is

Increasing performance and power efficiency in heterogeneous software

Heterogeneous architectures in embedded computing are fast becoming a reality – we indeed see many leading IP and semiconductor companies today building heterogeneous computing hardware. In the article below, I’m going to describe one typical use case for heterogeneous computing and the challenges that result from moving to
