Title: Image super-resolution and non-uniform blur removal method based on fusion network
Inventor: WANG FEI
IPC: G06T5/00
Filed: 2018-09-26
Abstract: Disclosed is an image super-resolution and non-uniform blur removal method based on a fusion network. The method realizes, for the first time, restoration of a low-resolution non-uniform motion-blurred image based on a deep neural network. The network uses two branch modules to respectively extract features for image super-resolution and non-uniform blur removal, and realizes adaptive fusion of outputs of two feature extraction branches by means of one feature fusion module that can be trained. Finally, an up-sampling reconstruction module realizes a non-uniform motion blur removal and super-resolution task. In the method, a self-generated training data set is used to perform offline training on a network, thereby realizing restoration of a low-resolution non-uniform motion-blurred image of any input size. The method is low in training difficulty, has a good effect, is extremely high in computing efficiency and is very applicable to restoration and enhancement, etc. of images photographed by mobile devices and monitoring devices.

Abstract: Embodiments of the present application provide a dielectric filter and a communication device. The dielectric filter comprises: a dielectric body, a first blind hole and a second blind hole provided in the dielectric body, a through hole located between the first blind hole and the second blind hole, and an insulating portion. Inner walls of the first blind hole, the second blind hole, and the through hole are covered with a metal layer, and the outer surface of the dielectric body is covered with the metal layer. The insulating portion is implemented by not covering the surface of the dielectric body with the metal layer, and the insulating portion partially surrounds the through hole. By means of the dielectric filter in the embodiments of the present application, when a signal wave entering the first blind hole passes through the through hole, a negative 90-degree phase shift occurs on the signal wave, and the signal wave is transmitted to the second blind hole, so that the dielectric filter achieves electrical coupling. Since it is a through hole that is formed between the first blind hole and the second blind hole, the means for achieving electrical coupling reduces the complexity of molding machining, and the means of electrical coupling does not have a parasitic resonance effect and does not affect low-end suppression.
