Infrared and visible image fusion (IVIF) aims to integrate complementary information between sensors and generate information-rich high-quality images. However, current methods mainly concentrate on the fusion of the source features from the sensors, ignoring the feature information mismatch caused by the property of the sensors, which results in redundant or even invalid information. To tackle th...Show More
Infrared and visible image fusion (IVIF) aims to obtain an image that contains complementary information about the source images. However, it is challenging to define complementary information between source images in the lack of ground truth and without borrowing prior knowledge. Therefore, we propose a semisupervised transfer learning-based method for IVIF, termed STFuse, which aims to transfer ...Show More
Defocus blur estimation requires high-precision detection between the homogeneous region and transition edge. This paper develops a novel progressive design that effectively addresses this challenge. Our multi-interactive scheme could gradually learn the characteristics of degraded input and divide complex defocus blur estimation into more manageable subnetworks. Specifically, we equally degrade t...Show More
Dimensional sentiment analysis (DSA) aims to recognize continuous real-valued annotations in multidimensional spaces such as valence-arousal space. It can serve as a sentiment analysis that is more fine-grained than traditional polarity classification. Existing methods primarily focused on supervised learning, which requires a large number of training samples. To address this issue, recent studies...Show More
This technical paper utilizes the Lyapunov theory to characterize the event-triggered set stabilizability of Markovian jump logical control networks (MJLCNs). Whereas the existing result for checking the set stabilizability of MJLCNs is only sufficient, this technical paper further establishes its necessary and sufficient condition. First, the Lyapunov function is established to describe the set s...Show More
This study proposes an infrared and visible image fusion method based on contrast saliency information guided, termed CSFusion. On the one hand, the gradual recovery network is devised to achieve self-refining processing and cross-stage integration of encoded features. Specifically, the network establishes one-to-one feature reuse between the encoder and the decoder, which can effectively facilita...Show More
With the development of image style transfer technologies, portrait style transfer has attracted growing attention in this research community. In this article, we present an asymmetric double-stream generative adversarial network (ADS-GAN) to solve the problems that caused by cartoonization and other style transfer techniques when they are applied to portrait photos, such as facial deformation, co...Show More
This work explores the $H_{\infty }$ synchronization issue for singularly perturbed coupled neural networks (SPCNNs) affected by both nonlinear constraints and gain uncertainties, in which a novel double-layer switching regulation containing Markov chain and persistent dwell-time switching regulation (PDTSR) is used. The first layer of switching regulation is the Markov chain to characterize the...Show More
Example-based texture synthesis requires synthesizing textures that are as similar as possible to the exemplar. However, for complex texture patterns, the existing methods lead to wrong synthesis results due to insufficient feature extraction capabilities. To address this problem, this paper proposed an optimized generative adversarial network model to address the quality issues such as low resolu...Show More
Medical image registration has always been a research hotspot in medical image processing. Compared with other fields (such as image segmentation), the training parameter space is very large and often lacks expert supervised correspondence annotations. These two challenges lead to slow image registration progress. We present a novel unsupervised medical image registration model, which incorporates...Show More
Attention mechanism plays a significant role in the current encoder-decoder framework of image captioning. Nevertheless, many attention mechanisms only fuse textual feature and image feature once, failing to adequately integrate the feature between context and image. Furthermore, many image captioning networks based on scene graphs only consider the node information but ignore the structure, which...Show More
A virtual try-on network has gradually become a popular topic in recent years. It aims to transfer images of in-shop clothes onto the image of a target person. Owing to the diversity of clothing attributes, developing an image-based virtual try-on network is a complicated task for computers to perform and requires significant effort. Existing methods are unsatisfactory as they cannot preserve the ...Show More
Multimodal medical image fusion (MMIF) is to merge multiple images for better imaging quality with preserving different specific features, which could be more informative for efficient clinical diagnosis. In this paper, a novel fusion framework is proposed for multimodal medical images based on multi-source information exchange encoding (MIEE) by using Pulse Coupled Neural Network (PCNN). We const...Show More
Postgraduate course teaching plays an important role in postgraduate education. With the development of “double first-class” construction and “new engineering disciplines”, it is imperative to reform the postgraduate course teaching, optimize the teaching system and improve the teaching effect. This paper takes the teaching of “image processing and computer vision” as an example to analyze and res...Show More
This paper presents a framework which is composed of a batik cloth model, a differential equation and an ellipse model for simulating batik cloth. The batik cloth model consists of three layers: wax layer, warp layer and weft layer. Warp and weft layer interlace between the wax layers. Based on Fick's second law, the differential equation is used to describe diffusion process and is discretized. E...Show More
This paper presents a fast implementation of multi-band blending for combining a set of registered images into a composite mosaic with no visible seams and minimal texture distortion. We first compute a unique seam image using two-pass nearest distance transform, which is independent on the order of input images and has good scalability. Each individual mask can be extracted from this seam image q...Show More
Most of the existing texture synthesis algorithms were proposed in the pursuit of the better synthesis quality or quick synthesis speed, but they could not satisfy requirements at the same time. In this paper, a new texture synthesis algorithm is presented. It adopts the color and the gradient as the similarity measurement of between the two matching patch, which improves their similarity extent. ...Show More

Color Transfer is used widely in the field of image processing. Color space and transfer algorithm need to be identified to complete color transfer. However, any one color space can not fit for all kinds of image and different transfer algorithms produce different effects. In this paper, three color spaces such as RGB, are used to achieve three color transfer algorithms and transfer effects are an...Show More
