With the rapid development of integrated circuits, its lead frame is increasingly high precision, which puts forward higher requirements for current research status and key technologies. In this paper, innovations structure control complex alloying, deformation, heat treatment high-precision frames manufactured by etching are reviewed. The relevant industrial chain at home abroad situation intr...

This paper proposes a method for key−frame selec−tion of captured motion data. Motion capture systems have been widely used in CG amusement and human motion analysis such as games and athlete training. For manipulation, retrieval and transmission, the compact motion is often required. Key−framing is often used to express CG animation with a compact set of frames. In general, the animation is de...

The quantum key distribution (QKD) allows two legitimate parties, Alice and Bob, to share secure keys based on the laws of physics. security BB84 protocol was proven in theory by many scientists. In QKD protocol, X-basis Z-basis used for encoding at Alice's end Bob's constitute their respective reference frames. Normally, Bob need same frame. If frames are inconsistent, system will not function...

We present a new approach for MPEG-2 video summarization and browsing based on the Growing Cell Structures (GCS) neural algorithms. Our system VideoGCS first applies GCS to select keyframes for each shot using the color histograms of the dc-images of I frames. These keyframes are then clustered by TreeGCS to form a hierarchical view of the video for efficient browsing. GCS is able to capture ve...

Human action is, in general, characterized by a sequence of specific body postures. An action is often recognizable from a single view of an action specific posture. In this paper we demonstrate that specific actions can be recognized in long video sequence by matching shape information extracted from individual frames to stored prototypes representing key frames of the action. The matching alg...
