MFSR pipeline consists of alignment, fusion, and reconstruction. We conduct a theoretical analysis using sparse coding (SC) and iterative shrinkage-thresholding algorithm to fill the gap of mathematical justification in the execution order of the optimal MFSR pipeline. Our analysis recommends executing alignment and fusion before the reconstruction stage (whether through deconvolution or SISR techniques). The suggested order ensures enhanced performance in terms of peak signal-to-noise ratio and structural similarity index. The optimal pipeline also reduces computational complexity compared to intuitive approaches that apply SISR to each input LR image.

To solve these problems, an underwater image enhancement network guided by brightness mask with multi-attention embedding, called BMGMANet, is designed. Specifically, considering that different regions in the underwater images have different degradation degrees, which can be implicitly reflected by a brightness mask characterizing the image illumination distribution, a decoder network guided by a reverse brightness mask is designed to enhance the dark regions while suppressing excessive enhancement of the bright regions. In addition, a triple-attention module is designed to further enhance the contrast of the underwater image and recover more details. Extensive comparative experiments demonstrate that the enhancement results of our network outperform those of existing state-of-the-art methods.

This is a critical problem, as often accessing high-quality high-resolution images is not guaranteed in real-life applications. In this paper, we propose a novel method for the task of joint image upsampling and hashing, that uses a three-stage design. Specifically, in the first two stages of the proposed scheme, we obtain two deep neural networks, each of which is individually trained for the task of image super resolution and image hashing, respectively. We then fine-tune the two deep networks thus obtained by using the ideas of representation learning and alternating optimization process, in order to produce a set of optimal parameters for the task of joint image upsampling and hashing. The effectiveness of the various ideas utilized for designing the proposed method is demonstrated by performing different experimentations.

However, due to the limited number of samples, many few-shot segmentation models suffer from poor generalization. Prototypical network-based few-shot segmentation still has issues with spatial inconsistency and prototype bias. Since the target class has different appearance in each image, some specific features in the prototypes generated from the support image and its mask do not accurately reflect the generalized features of the target class. To address the support prototype consistency issue, we put forward two modules: Data Augmentation Self-knowledge Distillation (DASKD) and Prototype-wise Regularization (PWR). The DASKD module focuses on enhancing spatial consistency by using data augmentation and self-knowledge distillation. Self-knowledge distillation helps the model acquire generalized features of the target class and learn hidden knowledge from the support images. The PWR module focuses on obtaining a more representative support prototype by conducting prototype-level loss to obtain support prototypes closer to the category center.

The main reason is that small objects are often affected by multi-layer convolution and pooling, leading to insufficient details to distinguish them from the background or similar objects, resulting in poor recognition rates or even no results. This paper presents a network architecture, Transformer-CNN, that combines a self-attention mechanism-based transformer and a convolutional neural network (CNN) to improve the recognition rate of SOD. It captures global information through a transformer and uses the translation invariance and translation equivalence of CNN to maximize the retention of global and local features while improving the reliability and robustness of SOD.

Additionally, we incorporate cluster labels to further refine the feature extractor, utilizing K-means clustering to assign these labels to unlabeled data, providing valuable supervision.

The proposed TAPOS preserves the image continuity of the original tensor and enhances the low-rankness of the generated higher-dimensional tensors, and a weighted de-augmentation method is used to assign different weights to the elements of sub-blocks and further reduce the block artifacts. To further alleviate the block artifacts and improve reconstruction accuracy, TV is introduced in the TAPOS-based model to add the piecewise smooth prior.
