Accurately detection of logos in media content on media presentation devices is addressed. Logos and products are detected in media content produced in retail deployments using a camera. Logo recognition uses saliency analysis, segmentation techniques, and stroke analysis to segment likely logo regions. Logo recognition may suitably employ feature extraction, signature representation, and logo matching. These three approaches make use of neural network based classification and optical character recognition (OCR). One method for OCR recognizes individual characters then performs string matching. Another OCR method uses segment level character recognition with N-gram matching. Synthetic image generation for training of a neural net classifier and utilizing transfer learning features of neural networks are employed to support fast addition of new logos for recognition.

Logo recognition in images and videos

Methods, apparatus, systems and articles of manufacture of logo recognition in images and videos are disclosed. An example method to detect a specific brand in images and video streams comprises accepting luminance images at a scale in an x direction Sx and a different scale in a y direction Sy in a neural network, and training the neural network with a set of training images for detected features associated with a specific brand.

A device may include a communication circuitry configured to receive device data from a paired device and a processor coupled to the communication circuitry. The processor may be configured to determine an ambient condition including physical presence of a user of the paired device relative to the paired device using to the device data. The device may also include a screen coupled to the processor. The screen may be configured to display an avatar of the user of the paired device and adjust a visual characteristic of the avatar responsive to the physical presence.
