In cloud storage applications, data owners' original images are usually encrypted before being outsourced to the cloud for preserving data owners' privacy. However, in deep learning model-based image encryption methods, an adversary can conduct the model extraction attack to reveal the model parameters and thus restore the privacy information by obtaining numerous encrypted images. In this paper, we propose an image translation-based deniable encryption (ITDE) scheme to achieve encryption deniability and defend against model extraction attacks. Differing from traditional encryption methods in which encrypted images are visually meaningless, ITDE applies image translation to generate encrypted images in the form of human faces. Moreover, ITDE provides deniability for data owners to keep the encryption parameters private. To defend against model extraction attacks, the defense mechanism is introduced in our proposed ITDE to preserve deep learning models. Experimental results demonstrate the superiority of our proposed methods in terms of encryption deniability and privacy preservation.

Generating high-quality stitching images with a natural structure is a challenging task in computer vision. Recent image stitching methods based on warps failed to suppress the distortion of the images. They often bend the salient lines in the image, which is inconsistent with human perception. In this paper, we succeed in proposing a novelty model called multi-perspective warps for natural image stitching which is related to the density of feature points in the images. With it we can get more precise matching results. Three new energy terms are developed to stitch quality to specify and balance the expected for aligning the vertices of the multi-scale mesh, which can constrain the transformation of the mesh. We also explore and introduce three feature point reconstruction algorithms to enrich the features in the images. Extensive experiments demonstrate that the proposed method outperforms most state-of-the-arts by effectively preserving the linear structure in the image and improving the robustness.

Deep metric learning for vision is trained by optimizing a representation network to map (non-)matching image pairs to (non-)similar representations. During testing, which typically corresponds to image retrieval, both database and query examples are processed by the same network to obtain the representation used for similarity estimation and ranking. In this work, we explore an asymmetric setup by light-weight processing of the query at a small image resolution to enable fast representation extraction. The goal is to obtain a network for database examples that is trained to operate on large resolution images and benefits from fine-grained image details, and a second network for query examples that operates on small resolution images but preserves a representation space aligned with that of the database network. We achieve this with a distillation approach that transfers knowledge from a fixed teacher network to a student via a loss that operates per image and solely relies on coupled augmentations without the use of any labels. In contrast to prior work that explores such asymmetry from the point of view of different network architectures, this work uses the same architecture but modifies the image resolution. We conclude that resolution asymmetry is a better way to optimize the performance/efficiency trade-off than architecture asymmetry. Evaluation is performed on three standard deep metric learning benchmarks, namely CUB200, Cars196, and SOP. Code: https://***/pavelsuma/raml

Approximately, 350 million people, a proportion of 8%, suffer from color vision deficiency (CVD). While image generation algorithms have been highly successful in synthesizing high-quality images, CVD populations are unintentionally excluded from target users and have difficulties understanding the generated images as normal viewers do. Although a straightforward baseline can be formed by combining generation models and recolor compensation methods as the post-processing, the CVD friendliness of the result images is still limited since the input image content of recolor methods is not CVD-oriented and will be fixed during the recolor compensation process. Besides, the CVD populations can not be fully served since the varying degrees of CVD are often neglected in recoloring methods. Instead, we propose a personalized CVDfriendly image generation algorithm with two key characteristics: (i) generating CVD-oriented images aligned with the needs of CVD populations;(ii) generating continuous personalized images for people with various CVD degrees through disentangling the color representation based on a triple-latent structure. Quantitative and qualitative experiments indicate our proposed image generation model can generate practical and compelling results compared to the normal generation model and combination baselines on several datasets.

Breast cancer is one of the most common types of cancer among women. It occurs when abnormal cells in the breast grow and divide uncontrollably. Early diagnosis and treatment are crucial in preventing its spread to the rest of the body. In this paper, we propose a ConvMixer-UNet network for ultrasound image segmentation. The objective is to identify the lesion in the ultrasound image. We design our network that consists of convolutional layers at the early level and ConvMixer layers at the latent level. ConvMixer is an extremely simple and parameter-efficient module that incorporates depthwise and pointwise convolutional layers. This model was evaluated using a breast ultrasound dataset (BUSI);it achieved an improvement in the value of Intersection over Union (IoU). We achieved 68.17% IoU and 80.60% Dice score. These scores are obtained via careful tuning for the network hyperparameters. Quantitative and qualitative comparisons ensure the value of our proposed network. Moreover, ConvMixer-UNet is considered a lightweight network compared to the leading medical segmentation network UNet and its extensions. We show that our network provides a significant reduction in the number of parameters to only 1.77 M parameters, in contrast to UNet which has 31.1 M parameters.
