摘要： A method for identifying traffic sign is provided. The method obtains an original image of a traffic sign, and performs an image enhancing processing on the original image to form an enhanced image. The method performs a first conversion on the original image and the enhanced image to together form a first matrix of image data, and identifies a position of the traffic sign accordingly. The method further masks the original image and the enhanced image respectively to form a first identified region of the original image and a second identified region of the enhanced image accordingly. The method further performs a second conversion on the first identified region and the second identified region to together form a second matrix of the identified region of the image data, and identifies passage instruction information of the traffic sign accordingly.

摘要： In a method of distinguishing objects in images, a first image segmentation model is applied to segment a first segmented image including a first object from a test image. A second image segmentation model is applied to segment a second segmented image including a second object from the test image. A third segmented image marking the first object and the second object is obtained according to first coordinates of the first object in the first segmented image and/or second coordinates of the second object in the second segmented image. The method can segment different objects from an image quickly and accurately.

摘要： An anti-counterfeiting structure to prevent tampering or replacement of the authenticated product of a packaging box includes a fixing member, a connecting member, a first mounting member, a second mounting member, and an anti-counterfeiting member. The connecting member connected to the fixing member defines a first receiving groove. The first mounting member is disposed in the first receiving groove and defines a second receiving groove. The anti-counterfeiting member in the second receiving groove includes an electronic screen and a battery disposed on the electronic screen. The first mounting member can be readily moved along a first direction away from the connecting member, driving the electronic screen along the first direction and thereby separating the battery from the electronic screen, causing cancellation of the structure and the visible authenticity of the product within the packaging box.

摘要： A method for detecting defects in product applied in a computer device inputs an image of a product under test to an automatic encoder to obtain a reconstructed image, and the image is segmented into N image blocks and the reconstructed image is segmented into N image blocks. The computer device associates each of the N testing blocks with one reconstructed blocks according to positions of the N testing blocks in the image and positions of the N reconstructed blocks in the reconstructed image. The computer device further calculates mean square errors between each of the N testing blocks and each of the N reconstructed blocks, and associates each mean square error with each of the N testing blocks, whether the product has defects being determined based on the mean square errors corresponding to each of the N testing blocks.

摘要： A head-mounted device comprises a main body, a monitor-base, at least one monitor, and a sensor. The main body is mounted on a head. The monitor moves with the monitor-base. The sensor is mounted on the main body or the monitor-base and used for detecting a state of the head. A visual field is defined as a maximum area seen by eyes of the user, and an area of the virtual image is smaller than the visual field. The at least one monitor is movable by moving the monitor-base relative to the main body according to the state of the head, detected by the sensor, to adjust a relative angle of the monitor to the eyes such that a relative position of the virtual image in the visual field is adjusted, to ensure that the user sees the virtual image. An augmented reality device is also disclosed.

摘要： A method of detecting defects revealed in images of products obtains sample image training data. An underlying feature dimension of an autoencoder is selected and a score is obtained. By comparing the score with a standard score, an optimal underlying feature dimension is confirmed. A test image is inputted into the autoencoder with the optimal underlying feature dimension to obtain a reconstruction image. A reconstruction error between the test image and the reconstruction image is computed. By comparing the reconstruction error with the predefined threshold a result of analysis of the test image is outputted. An image defect detection apparatus and a computer readable storage medium applying the method are also provided.
