In order to realize the miniaturization and lightweight of the infrared nonuniform correction shutter, the crank slider mechanism is used to design. Firstly, the shutter blade is used as the slider and the driving mechanism is used as the crank, and the motion analysis is carried out. The transmission angle of the crank slider mechanism is calculated to be no less than 66.42 °. Then, the slider, connecting rod and crank are analyzed respectively, the force system and motion equation are established, and the driving torque of the shutter is calculated. The design results show that the volume, weight and driving torque of the same target product are reduced by 1 / 3, 1 / 2 and 1 / 2, respectively, compared with the direct motion rotary shutter commonly used in nonuniform correction of infrared camera. The design goal is achieved.

In recent years, the rapid development of mixed-precision quantification technology has greatly reduced the scale of the model and the amount of calculation. However, the previous mixed bit-width strategies are too complicated, such as reinforcement learning strategies and Hessian matrix strategies. This paper proposes an efficient mixed bit-width searching strategy, which measures the sensitivity of the convolutional layer by the scale factors of the BN layer. The advantage of this strategy is that the parameters of the pre-trained model are used and no extra computation is introduced, which greatly simplifies the complexity of the bit-width selection strategy. In this paper, Resnet18 and Resnet50 models are used to conduct comparative experiments, and the differences between the proposed strategy and several previous algorithms are compared in terms of accuracy, model size and computation amount. It is verified that the accuracy of quantization in this paper is reduced within 2% compared with FP32 baseline, and the accuracy is reduced with about 0.5% compared with HAWQ. Overall, the performance is similar to that of HAWQ. This paper also compares the calculation complexity of the quantized bit-width of HAWQ-V3 with the calculation complexity of the quantized bit-width of this paper, which proves that the computational complexity of the strategy in this paper is far less than that of HAWQ-V3.

Our study is to improve the accuracy of bone morphology depicted in dental cone-beam computed tomography (CBCT) images. First, successive statistical iterative reconstruction was used to reduce unavoidable streak artefacts. Then 3-dimentional filtering (Gaussian-Laplacian filter) and region growing methods were examined to present clear bone morphology. CBCT examinations were performed with the following principal exposure parameters: I-mode, FOV 10cm in diameter, 120 kV, 15 mA, 0.2 mm slice thickness, and exposure time of 10s. Ordered subset-expectation maximization (OS-EM) algorithm was applied for unavoidable streak artefact reduction. 3D Laplacian sharpening to images preprocessed by Gaussian smoothing was sequentially tested. Region growing method with dilation and erosion was used to segment maxillofacial tissue. Streak artefact induced by metallic prosthetic appliances was reduced by applying successive iterative OS-EM algorithm. Multi-planar reconstruction (MPR) images at left side molar plane and mid-sagittal plane were presented to validate effect of OS-EM algorithm and 3D Gaussian-Laplacian filter. Maxillofacial tissue was segmented and presented to show the effect of region growing method. Streak artefact reducing method, 3D filtering method for image smoothing and sharpening, and region growing method with dilation and erosion were effective to improve accuracy of bone morphology in dental CBCT images.

Due to the limitation of the device, pictures taken in low-light environment usually consist of unpleasant deterioration, such as low contrast and color distortion. In this paper, we propose a Multi-scale Deep Curve Estimation network (MSDCE) for low-light image enhancement, which formulates the single low-light image enhancement task as a pixel-wise curve estimation by paired learning. To impose more priors of low-light regions, we propose an inverse illuminance map as part of the Curve Estimation network input. The curve estimation network backbone is composed of multi-scale modules which learns information from multi-scale feature streams and ensures the information exchange across different scales. Compared with several state-of-the-art methods, our method is significantly better. From the perspective of visual evaluation, our MSDCE can effectively improve the contrast and illumination of the image, and ensure the color fidelity of the image.

At present, the application of computer vision technology in power systems is increasing. The idea of using image processing and machine vision to monitor power equipment is not new. However, the research mainly focuses on the application of computer vision technology in the fields of transmission line environment and insulator detection. Combined the actual conditions of the intelligent grid substation and the need of construction, this paper proposed and studied a kind of identification algorithm based on intelligent computer vision technology, aiming at solving the problem of automatic identification of typical outdoor circuit breakers, disconnectors and indoor switchgear.

Filtering off speckle noise while preserving fine details for optical coherence tomography(OCT) is particularly challenging. In this paper, an efficient method based on variational image decomposition(VID) is proposed to suppress speckle from OCT retinal images. A new BL-G-BM3D model based on VID is proposed to decompose one OCT retinal image into the background part, the texture part and noise. Each part is described by suitable function space separately and processed individually. The proposed model is able to preserve structural information while sufficiently suppressing speckle noise. We test the proposed method on two raw OCT retinal images with low contrast and high noise level, and compare with four other related and widely used filtering methods in terms of both quantitative evaluation and visual quality.The experimental results have demonstrated the validity of the proposed method.

A method for volumetric dataset registration that utilizes principal component analysis (PCA) and volumetric extended Gaussian image (EGI)-based processing is presented. The method uses PCA to determine an initial coarse estimate of orientation difference between two volumetric datasets. The PCA is based on certain automatically selected (i.e., significant) voxels. The coarse estimate then is refined by a three-stage process that utilizes enhanced volumetric extended Gaussian images (EV-EGIs). These final EV-EGI stages also provide the translational component. The method's combination of steps allows for faster processing at roughly similar accuracy versus prior work based solely on EV-EGIs. Experimental comparisons with Globally optimal Iterative Closest Pointset (Go-ICP) registration are also reported and analyzed.

In order to improve the effectiveness of rehabilitation of stroke patients, active training can be used to treat and recover the patient's foot dyskinesia. Recognizing the different movement characteristics of the feet is an important part of the active rehabilitation of stroke patients. In this paper, the EMG signals of different movements of the right foot are classified and studied. The EMG signals of three different movement states of the foot resting state, foot stretched 15° and foot stretched 45° are collected, absolute mean and filter common space mode were used for feature extraction of EMG signal, and support vector machine (SVM) was used for classification and recognition after extraction. The experimental results show that the classification accuracy rate of resting state-foot-stretched 45° is 89.9%, which exceeds the classification accuracy rate of resting state-foot-stretched 15° of 86.8%. It shows that when the subjects stretch the foot at 45°, more motion units are activated and the characteristics are more obvious than when the feet are stretched at 15°. Therefore, by classifying the characteristics of EMG signals and identifying different autonomic movements of feet, it can be used as the basis for rehabilitation treatment of stroke patients. At the same time, the average classification accuracy of 15° -45 ° and the resting state -15 ° -45 ° is above 80%, which confirms the feasibility of the signal processing method and support vector machine classification algorithm used in this paper for the study of automatic foot motion recognition.
