This chapter speaks to the ways in which reform cinema was wrapped up in the technological changes during Khatami’s presidency. In particular, video technology, which was banned in Iran between 1982 and 1993, gained widespread acceptance during Khatami’s presidency. Meanwhile, the proliferation of digital video at the beginning of the 21st century was changing what it meant to make and watch movies around the world. Abbas Kiarostami’s Taste of Cherry (1997) and Ten (2002) and Bahman Farmanara’s The Smell of Camphor, the Scent of Jasmine (2001) speak to this changing technology, and they play with video in order to show how this technology was democratizing filmmaking in Iran. This chapter contextualizes Kiarostami’s and Farmanara’s films by suggesting a history of video technology in Iran, one which demonstrates that the changing cultural value of video developed in tandem with Khatami’s discourse of reform.

The paper briefly sums up the digital video panorama stitching steps, core issues and common registration algorithm on the base research of panoramic digital video technology. Also image registration algorithm based on feature line segment ratio is applied to educational panoramic digital video production. Examples have shown that the algorithm has good results in convergence rate, accuracy, and workload and so on, which has proved valuable in the digital video research. The advantages and disadvantages of the algorithm are summarized for the further study.

Intended Use

Abstract Context.—Digital technology is commonly used for documentation of specimens in anatomic pathology and has been mainly limited to still photographs. Technologic innovations, such as digital video, provide additional, in some cases better, options for documentation. Objective.—To demonstrate the applicability of digital video to the documentation of surgical specimens. Design.—A Canon Elura MC40 digital camcorder was used, and the unedited movies were transferred to a Macintosh PowerBook G4 computer. Both the camcorder and specimens were hand-held during filming. The movies were edited using the software iMovie. Annotations and histologic photographs may be easily incorporated into movies when editing, if desired. Results.—The finished movies are best viewed in computers which contain the free program QuickTime Player. Movies may also be incorporated onto DVDs, for viewing in standard DVD players or appropriately equipped computers. The final movies are on average 2 minutes in duration, with a file size between 2 and 400 megabytes, depending on the intended use. Because of file size, distribution is more practical via CD or DVD, but movies may be compressed for distribution through the Internet (e-mail, Web sites) or through internal hospital networks. Conclusions.—Digital video is a practical, easy, and affordable methodology for specimen documentation, permitting a better 3-dimensional understanding of the specimens. Discussions with colleagues, student education, presentation at conferences, and other educational activities can be enhanced with the implementation of digital video technology.

This article examines the role of digital video in fashion research. It makes a case for the use of digital video as a valuable tool within the suite of research methods typically used in the field of fashion and dress. Its aim is to demonstrate that digital video can enrich studies of fashion, specifically in its capacity to assist the capture and analysis of visual material unavailable to unmediated perception. Central to this is the technology’s ability to document the dressed body in movement. The article discusses outcomes of a video-based methodology with reference to participatory research activities termed ‘sartorial sessions’. The approach used digital video technology to make possible the collection, analysis and manipulation of embodied material for a close interpretation and analysis as well as for others to encounter. The article demonstrates the way digital media, when used in conjunction with practice-oriented methods, opens up new ways to understand and research the body in fashion. It concludes with reflection on how revelation of a background sartorial vitality opened up by digital technology can shift understanding of fashion from commodities or signs involved in the transmission of messages about wearers, or aesthetic propositions to powerful tools shaping our encounters in the world.

Basketball Shooting

Aiming at the difficulty of standardizing the action of basketball shooting training, a new method of standardizing the action of basketball shooting training is proposed based on digital video technology. The digital video signal representation, video sequence coding data structure, and video sequence compression coding method are analyzed, and the pixels of basketball shooting training action position space are sampled to collect basketball shooting training images. The time difference method is used to extract the movement target of basketball shooting training from a digital video sequence. Based on digital video technology, the initial background image is estimated, and the update rate is introduced to update the background estimation image. According to the pixel value sequence of the basketball shooting training image, the pixel model of the basketball shooting training image is defined and modified. By judging whether the defined pixel value matches the background parameter model, the standardization of shooting training can be realized. The experimental results show that the proposed method has good stability, high precision, and short time in determining the standardization of shooting movement, can correct the wrong shooting movement in real time, and can effectively guide basketball shooting training.
