Thin Client Application – Photobook Creation

The Virtual (“Hybrid”) Cloud Imaging Server

Public Clouds (External) Printer Clouds (External) Image De-noising Enterprise / Digital Home Frog’s Cloud Imaging Server

Server Features:

Photo Book Creation using Image Processing Algorithms:

• Image De-Noising
• Panorama Stitching
• Low Light Enhancement
• Vivid colour effect
• Noise reduction
• White Balance

Base Station (Femto Cell)

Concept:

Photobook creation is one of the most technically challenging workflows for “Photo Product” solution. These problems are only magnified when the authoring platform is expanded beyond PCs to mobile and social platforms. Our “Auto Photo book creation” with “Cloud Imaging Server” uses core imaging algorithms to streamline the workflow and automate many of the more cumbersome steps, which both simplifies the creation process and makes it more amenable for mobile devices and social networks

Today’s Problem Statement:

Multimedia information such as “Photos and Videos” are increasingly viewed and shared through social networking sites such as “YouTube and Facebook”. In Today’s Scenario, the users even don’t have time to organize their photos and videos on their Handheld devices. Many users on day-2-day life snap/capture large numbers of photos either from Mobile (or) from Digital Camera to capture events in their lives, but only a very small fraction of Photos are tagged. Although online sharing makes the content easier to access, users continue to face many challenges in dealing with multimedia operations.

Content Adaptation Gateway - Features

Features Description Benefits

Video Optimization Optimize video properties like framerate, resolution etc based on client capability and human perception Avoiding client side overheads like Scaling. Adaptive Video Transrating Change the Video Bitrate dynamically according to network conditions. Increases quality of user experience by reducing stalls (rebuffering). Client Adaptation Gateway detects each device and its video profile using a database of device profiles. Different devices have different profiles - screen sizes, resolutions, CPUs, players, and codecs and levels. Optimize Bandwidth

and codecs and levels. Content Caching Caching reduces upstream operating expenses by storing data in temporary memory for local distribution. Caching saves multiple retrievals of the same video from content distributors, which saves bandwidth in the upstream link and minimizes operating expenses. Network Monitoring Determine optimization parameters based

• n subscriber, content & network conditions

(Operator n/w & client connection). Ensures optimization occurs according to network conditions. Video pacing - Just-In-Time Delivery Transmit data as per client buffer size to enable smooth playback. Transmit data as per encoding rate of video. Eliminates wasted downloads of entire video in cases where user watches only initial portion. Video Smoothing Effective video transmission of variable bitrate video Avoid Bandwidth fluctuations
