Abstract: In a system that reduces interference between devices that transmit infrared signals, a first device transmits a first infrared signal to a second device during a first time period. The second device determines a command encoded by the first infrared signal. When the first time period has elapsed, the first device ceases transmission during a second time period. The second device transmits the second infrared signal to a third device during the second time period. As a result, transmissions from the second device to a third device are not affected by interference from transmissions by the first device. Selected signals from the first device may be permitted during the second time period, such as signals to cancel previous commands or to queue additional commands.

Abstract: Real-world data may not be sparse in a fixed basis, and current high-performance recovery algorithms are slow to converge, which limits compressive sensing (CS) to either non-real-time applications or scenarios where massive back-end computing is available. Presented herein are embodiments for improving CS by developing a new signal recovery framework that uses a deep convolutional neural network (CNN) to learn the inverse transformation from measurement signals. When trained on a set of representative images, the network learns both a representation for the signals and an inverse map approximating a greedy or convex recovery algorithm. Implementations on real data indicate that some embodiments closely approximate the solution produced by state-of-the-art CS recovery algorithms, yet are hundreds of times faster in run time.

Abstract: A method for embedding the spread spectrum watermark into images with the self-adaptive embedding strength includes the following steps: designing a spread spectrum watermark capable of completely shielding a host signal interference by using prior knowledge of the host signal interference, self-adaptively adjusting a value of an embedding strength in the spread spectrum watermark with different host images, ensuring imperceptibility of each image while simultaneously maximizing robustness of the watermark, and finally embedding the spread spectrum watermark in the host image. The present disclosure can not only completely shield the host signal interference but also effectively withstand various common image processing attacks and geometric attacks, and at the same time, all the watermarked images can obtain consistent imperceptibility. The present disclosure can be applied to various watermarking techniques based on discrete cosine transform.

Abstract: Disclosed are a method and device for transmitting image data, a storage medium, and a processor. The method comprises: segmenting a target image into multiple regional images having different resolutions, wherein the target image comprises a first regional image and a second regional image, the first regional image is an image in a region on which a gaze point falls, and the second regional image is a regional image other than the first regional image in the target image; and transmitting header information of the multiple regional images and pixel values of respective pixels in the respective regional images. The present invention solves a technical problem in which since image data in multiple formats are transmitted in practice and each image data transmitting apparatus can only transmit image data in a certain format, such format limitation results in poor compatibility between image data transmitting apparatuses.

Abstract: An image processing device 1 selects, from among images in which an object to be sensed is captured, a representation image which is a reference for processing. In a state of the representation image being selected, the image processing device carries out a comparative analysis between the representation image and the image which differs from the image which has been selected as the representation image, and thereby computes a degree of displacement between the representation image and the image. From among the images which have been assigned as reference images, the image processing device selects the reference image which will be used in a process of analyzing the movement of the object to be sensed, on the basis of the degree of displacement which has been computed.
