IPC: G06T7/00
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To realize efficient graphic sort and retrieval resistant to noise or local deformation. SOLUTION: In this graphic sorting method, a graphic is inputted (100), its structural features are extracted (105), transformation rules are applied to the extracted structural features and the structural features of a transformed graphic are composed (110). Otherwise, the structural features of a graphic rotating the input graphic at a certain angle every time and its inverted graphic are extracted and the transformation rules are applied to these features. An index is calculated from these respective structural features and while referring to the model identifier list of a correspondent entry on a sort table 120, polling operation is performed (115).  While using values multiplying the similarity of the input graphic and a model concerning the degree of complexity, area, length and circular degree of the graphic to the polling score of each model as similarity scores, the several models high in similarity score are selected as sort candidates (116).

Title: Chip enable signal control circuit in dual port memory element
Inventor: CHIYAN HIYUNNSU
IPC: G11C11/401
Filed: 1990-09-06
Abstract: PURPOSE: To increase a data transmitting margin and to prevent malfunctions by inputting a clock signal assigning the output signal from a switching means and the completion of data transmission and providing with a latch means outputting a clock signal being a master clock inside a tip. CONSTITUTION: When a first clock signal CLK1 is in a H state, since a signal in a L state is outputted with a fourth NOR gate NO4 , a second clock signal CLK2 outputted from a third NOR gate NO3 becomes inverted signal to the output signal of a second inverter 12 and becomes L state. Next, when the signal CLK1 is transited to the L state, the signal in the H state is outputted with the gate NO4 . In this case, since the signal CLK2 is maintained in the L state regardless of the state of a signal RAS, the active state of the signal CLK2 becomes longer than the signal RAS. By this way, a data transmitting time between dual ports is compensated, the transmitting margin becomes large, and also the data transmission is correctly executed in a prescribed time.
