MELF (Metal Electrode Leadless Face) component positioning and detecting method based on match template

The invention discloses a MELF (Metal Electrode Leadless Face) component positioning and detecting method based on match template which belongs to the technical field of component positioning and detecting. Under a traditional match template algorithm, it takes great amount of computing to detect a component with a rotation angle, and the process is also very slow to perform. For these reasons, the positioning and detecting speed for the component is also rather slow. In light of these shortcomings, the invention provides a MELF (Metal Electrode Leadless Face) component positioning and detecting method. The method creates a template image with angle to obtain a distance transformation image of a narrowed image of the component and a distance transformation image of the original image of the component and to obtain a final best match template image and a best match position. Key edge points are extracted from an edge image with interference points to form a minimum external rectangle. According to the number of the non-zero pixels in the minimum external rectangle with added offset value, the method determines that the positioning of the component is correct and that the length and the width of the component are in the bearable range. After that, the positioning and detecting process is complete and positioning information of the component is then transmitted out. The method provided by the invention is capable of reducing the number of positions searched during the computing of a match template value. With the method, the computing efficiency of a match template can be increased and the accurate rate for positioning and detecting reaches 95% to 98%.

Portable telephone

A portable telephone has a phone-book capability of storing and searching plural pieces of receiver information including character information and image information and comprises phone-book memory means for registering plural pieces of receiver information including character information and image information associated with each other; decoding means for decoding the image information stored in the phone-book memory means; display means for displaying the character information and the image information stored in the phone-book memory means; operation means for outputting a select signal in accordance with an external operation; and control means for controlling the phone-book memory means, the decoding means, the display means, and the operation means. The control means performs such control that when a plurality of select signals for selecting different pieces of receiver information from that receiver information which is currently displayed on the display means are output from the operation means continuously or over a given period of time, those character information which are included in the selected pieces of receiver information are sequentially displayed on the display means in accordance with the select signals and only that image information which corresponds to a last select signal output is decoded by the decoding means and is displayed on the display means.

Automatic way-finding method in game

The invention provides an automatic way-finding method in a game. The automatic way-finding method comprises the following steps: S1: dividing a game map into meshed way-finding points, wherein at least one way-finding point is an obstacle point; S2: selecting the two way-finding points as a starting point and a target point, and taking the starting point as a current way-finding point; S3: searching a next way-finding point in the direction from the current way-finding point to the target point, and judging whether the next way-finding point is the obstacle point or not; S4: if the next way-finding point is not the obstacle point, judging whether the next way-finding point is the target point; S5: if the next way-finding point is the obstacle point, taking a searching path as a way-finding path; if the next way-finding point is not the obstacle point, taking the next way-finding point as the current way-finding point, and carrying out the step S3; and S6: if the next way-finding point is the obstacle point, searching the next way-finding point in the left and right directions of the obstacle point, and taking the next way-finding point as the current way-finding point and carrying out the step S3. By the aid of the automatic way-finding method, the search, which is not related with the way-finding point, can be reduced and the searching efficiency is improved.

Rapid motion estimation self-adaptive selection method based on motion complexity

The invention relates to a rapid motion estimation self-adaptive selection method based on motion complexity. Firstly, according to the time continuity of a video sequence, the frame level judgment of motion complexity is carried out taking the motion complexity of the image of a previous frame as the basis; then according to the result of the frame level judgment, the judgment of macro-block level motion complexity is carried out on image frames required to continue the judgment according to the space correlation of the video sequence; and finally, the motion estimation is carried out on the current macro-block to select the motion estimation method according to the judgment of the motion complexity for the frame level and macro-block level. On the basis of the analysis for the advantages and disadvantages of the diamond search method and the motion estimation method, the invention utilizes the complementarity of the existing methods, combines the self-adaptive threshold value and the judgment of premature termination conditions to select suitable search method through the calculation of the frame-level motion complexity and macro-block level motion complexity of the video sequence. Experiment results show that the invention can achieve the purpose of rapid motion estimation on the precise of guaranteeing the image quality.

The application discloses an acquisition method of a coding starting point and an acquisition device of the coding starting point. The acquisition method of the coding starting point comprises the following steps: acquiring a motion vector of a prediction unit; acquiring location information of a to-be-coded unit in the current frame; acquiring a location same as the location information of the to-be-coded unit in a first reference frame corresponding to the to-be-coded unit; and performing offset on the location according to the motion vector, and determining the starting point of the to-be-coded unit in the reference frame. Through the technical scheme disclosed by the application, a motion estimation starting point is set according to actual motion situation through the existing motionvector, the starting point is closer to the real motion vector, the fixed motion search range can be shrunk, the real motion vector can be found by performing small-scale searching by taking the starting point as a center, so that the image quality and the video code rate can be maintained unchanged basically, the searching in an overall big window is avoided, the searching process is reduced, andthe time for motion estimation is reduced, thereby reducing the coding time and improving the coding efficiency.
