Product information display and purchasing

Abstract: A method of providing additional information to a viewer of a moving image file is disclosed. The method includes the steps of providing one or more tags within the moving image file indicating the existence of additional product information; visually indicating the existence of the tags alongside or over the moving image; detecting a request to view the product information associated with the one or more tags; pausing the moving image; and displaying the requested product information over the paused image.

Printing web page images Via a marked proof sheet

Abstract: A printing system and method for printing selected images on a web page The web page is automatically analyzed to identify image files associated with the web page, and the image files are automatically filtering according to predetermined criteria so as to identify qualified image files At least one of the qualified image files is selected for printing, and then printed A proof sheet having an image identifier and a corresponding selection area or image specifier for each image file may be printed Selection areas of the proof sheet can be marked to indicate the image files to be printed and then optically scanned to detect the images selected for printing, or the image specifiers can be entered into the printing system to specify the images selected for printing

Endoscope video apparatus

Abstract: An endoscope video apparatus has an endoscope including a solid-state image sensor, for outputting an endoscopic image signal, a video processor for processing the image signal supplied from the solid-state image sensor and outputting a video signal, an image file unit for recording the video signal, and an input section for inputting retrieval data corresponding to the video signal recorded in the image file unit. A control section discriminates the presence/absence of retrieval data input from the input section. A control circuit operates an alarm unit by discrimination data representing the absence of retrieval data.

Downscaling Factor Estimation on Pre-JPEG Compressed Images

Abstract: Resampling detection is one of the most important topics in image forensics, and the most widely used method in resampling detection is spectral analysis. Since JPEG is the most widely used image format, it is reasonable that the resampling operation is processed on JPEG images. JPEG block artifacts bring severe interference to spectrum-based methods and degrade the detection performance. In addition, the spectral characteristics of the downscaling scenarios are very weak. The detection of downscaling still presents a considerable challenge to forensic applications. In this paper, we propose a method to estimate the downscaling factors of pre-JPEG compressed images in the presence of image downscaling after JPEG compressions. We first analyze the spectrum of scaled images and give an exact formulation of how the scaling factors influence the appearance of periodic artifacts. The expected positions of the characteristic resampling peaks are analytically derived. For the downscaling scenario, the shifted JPEG block artifacts produce periodic peaks, which cause misdetection in the characteristic peak. We find that the interval between the adjacent extrema of difference images obeys the geometric distribution and the distribution has periodic peaks for JPEG images. Hence, we adopt the difference image extremum interval histogram and combine the spectral method to obtain the final estimation. The experimental results demonstrate that the proposed detection method outperforms some state-of-the-art methods.

Framework for real-time brokering of digital content delivery

Abstract: A method of transmitting digital content via a communication network. The method comprises receiving by a computer a request for a uniform resource identifier (URI), determining by a computer based on the request for the uniform resource identifier a communication service provider associated with a communication device, and when the communication service provider is affiliated with a digital content custom delivery offer building system, transmitting by a computer an image file to be presented by the communication device.
