Abstract

Mitochondrial segmentation in microscopic images is a complex task hindered by variations in mitochondrial size, color, texture, and their often ambiguous borders with surrounding tissue. To overcome these obstacles, we adapted Parallel Reverse Attention Network (Pranet), originally developed for precise polyp detection, to the domain of mitochondrial segmentation. Pranet employs Parallel Partial Decoder (PPD) to integrate multi-level features, producing a high-level context map that guides subsequent processing. The model further enhances segmentation precision through a Reverse Attention (RA) module, which adeptly identifies object boundaries by iteratively refining region-boundary interactions. Our approach was thoroughly evaluated on the EPFL dataset, yielding substantial improvements in segmentation accuracy. Additionally, Pranet demonstrated robust generalization and real-time performance, underscoring its suitability for comprehensive microscopic image analysis.

Abstract

Monocular depth estimation (MDE) has evolved into a vital research focus in visual computing and autonomous robotic systems. While recent deep learning approaches have advanced the field, existing methods often struggle to jointly incorporate global context and fine-grained local details, and may be hampered by complex, computationally expensive network architectures. To address these challenges, we employ the U2Net framework, which incorporates Residual U-Blocks designed to adapt the area of reception and capture multi-scale contextual data. By nesting U-shaped structures, U2Net effectively increases feature extraction depth while maintaining computational efficiency, thus offering a more balanced and scalable solution for MDE. Our proposed model, developed using the NYUDepth V2 dataset, exceeds contemporary methods in critical assessment measures, including RMSE, RMSE(log), and Absolute Relative Error (Abs Rel). These improved results highlight the robustness and precision of proposed model or a range of practical applications in robotics, augmented reality, and other domains requiring real-time scene geometry understanding.

Abstract

While Quantum Neural Networks (QNNs) offer the potential for resource-efficient image classification, practical implementations are hindered by qubit instability and finite availability, causing them to often underperform classical counterparts. This performance disparity constitutes a critical research gap. We propose a novel hybrid classical-quantum knowledge distillation approach to bridge this gap. Our method utilizes a pre-trained classical CNN (AlexNet) as a teacher to guide the training of a quantum student model by minimizing the Kullback-Leibler (KL) divergence (DKL) between their output distributions. The quantum student model employs an architecture designed to facilitate intricate feature interactions using iterated CNOT gates. This technique substantially improves quantum model accuracy, demonstrating gains of 0.34% (6-class, 3 qubits) and 0.28% (8-class, 3 qubits) on the MNIST dataset, and 0.74% (8-class, 4 qubits). Our contribution lies in operationalizing a knowledge distillation paradigm for applied Quantum Machine Learning (QML), enabling the effective transfer of robust knowledge from established classical architectures to resource-constrained quantum models, thereby enhancing faster convergence and accelerating practical QML deployment.

Abstract

This paper presents YESnet, a novel framework integrating the YOLOv11 object detector with the Segment Anything Model 2 (SAM-2) for memory-efficient skin lesion segmentation. The proposed architecture introduces: (1) An anchor-free YOLOv11 detection head that eliminates predefined bounding box priors while maintaining detection accuracy, (2) A memory-optimized SAM-2 variant that preserves boundary delineation capabilities through compressed feature retention, and (3) A lightweight co-processing pipeline that coordinates detection and segmentation stages without computational redundancy. Evaluated on the HAM10000 dataset, YESnet achieves competitive performance in lesion segmentation (96.00% accuracy, 92.38% Dice) while demonstrating efficient memory utilization. The framework's design enables effective lesion boundary capture with minimal parameter overhead, making it particularly suitable for resource-constrained clinical deployment scenarios.

Abstract

Road extraction from very high-resolution satellite imagery (VHR) is necessary for remote sensing applications like city management, and navigation. In this study, we introduce SE-U2Net, a novel deep learning model for precise road extraction. Our proposed model integrates the Squeeze and Excitation (SE) network with the U2 Net architecture for enhanced selective channel refinement and better contextual information capture. SE-U2Net employs Residual U-blocks (RSU), which combine receptive fields of different sizes, enabling the model to capture multiscale contextual data efficiently. The baseline U2Net has 75.06 GFLOPs and 37.51 GMacs, while SE-U2Net maintains this efficiency with 75.07 GFLOPs and 37.51 GMacs, despite its enhanced representational capacity through SE blocks. Emperical outcomes on the DeepGlobe dataset demonstrate that SE-U2Net outperforms the base U2Net model and other state-of-the-art models, achieving superior performance in terms of Dice coefficient, mean Intersection over Union (mIoU), precision, and recall. These results underscore SE-U2Net's potential as a robust tool for high-accuracy road segmentation from VHR satellite imagery.

Abstract

Road extraction from satellite imagery faces critical challenges in capturing contextual spatial relationships and mitigating background interference. We introduce DoubleUNet++, which improves the DoubleUNet architecture with two main enhancements: (1) A channel-aware gated attention (CAGA) mechanism in the skip connections of the second U-Net, dynamically weighting channel features via decoder gating signals, and (2) Squeeze-and-Excitation layers in the attention path for adaptive channel-wise feature recalibration. Evaluated on the CHN6-CUG dataset (4,511 annotated images), our model achieves state-of-the-art performance with 78.52 Dice score and 64.94 mIoU - representing 3.32 % and 3.74 % absolute gains over baseline DoubleUNet. Despite these improvements, DoubleUNet++ maintains similar computational complexity (109.33 GFLOPs, 54.64 GMacs) compared to the baseline (107.41 GFLOPs, 53.68 GMacs). The architecture maintains comparable complexity (29.5M parameters) while significantly improving precision (81.45% vs 73.78%) through refined spatial focus on roadrelevant regions. Qualitative analysis demonstrates the CAGA mechanism's effectiveness in reducing misclassification from nonroad objects such as vegetation and buildings while preserving road topology. These advancements establish DoubleUNet++ as a robust solution for large-scale road network mapping without requiring additional annotated data.

Abstract

Diabetic retinopathy (DR) poses a serious threat to vision, emphasising the need for early detection. Manual analysis of fundus images, though common, is error-prone and time-intensive. Existing automated diagnostic methods lack precision, particularly in the early stages of DR. This paper introduces the Soft Convolutional Block Attention Module-based Network (Soft-CBAMNet), a deep learning network designed for severity detection, which features Soft-CBAM attention to capture complex features from fundus images. The proposed network integrates both the convolutional block attention module (CBAM) and the soft-attention components, ensuring simultaneous processing of input features. Following this, attention maps undergo a max-pooling operation, and refined features are concatenated before passing through a dropout layer with a dropout rate of 50%. Experimental results on the APTOS dataset demonstrate the superior performance of Soft-CBAMNet, achieving an accuracy of 85.4% in multiclass DR grading. The proposed architecture has shown strong robustness and general feature learning capability, achieving a mean AUC of 0.81 on the IDRID dataset. Soft-CBAMNet's dynamic feature extraction capability across all classes is further justified by the inspection of intermediate feature maps. The model excels in identifying all stages of DR with increased precision, surpassing contemporary approaches. Soft-CBAMNet presents a significant advancement in DR diagnosis, offering improved accuracy and efficiency for timely intervention.

Abstract

Automated colonoscopic polyp segmentation, vital for early colorectal cancer detection, has notably advanced with deep learning. However, reliance on operator expertise and challenges posed by varied polyp sizes during training, along with limitations in representing long-range dependencies, warrant further refinement in the field. In this paper, we propose a novel transformer-based text guided architecture called TGA-TransNet to address these challenges. Particularly, the TGA-TransNet model incorporates size-related and polyp number-related information through text attention during training. Additionally, Transformer layers are utilized to extract global contexts. Our early experimental results on the popular Kvasir-SEG dataset indicate that the proposed integration of text embeddings and Transformer enhances the overall segmentation performance of the model, surpassing its state-of-the-art counter-part. Feature map analysis also suggests that our proposed TGA-TransNet demonstrates strong generalization capabilities across the variable-sized polyps.
