In recent years, with the development of the field of learned image compression, numerous models with excellent ratedistortion performance have emerged. However, the considerable computational complexity inherent in these models poses challenges for their practical deployment. In this paper, we investigate feature redundancy in learned image compression (LIC) algorithms for efficient feature extraction and introduce an efficient and lightweight LIC framework. Specifically, we explore the existence of a large number of similar features in the network. Subsequently, we design effective feature extraction modules across various levels, such as layer and block. In addition, based on the fact that the role of the codec's encoder is to remove redundancy and the decoder is to reconstruct, we propose an asynchronous feature fusion block. This fusion block incorporates an "edge smoothing" operator in the encoder and an "edge enhancement" operator in the decoder. Our methodology strikes an ideal balance between rate-distortion performance and efficiency. The experimental results indicate that our approach necessitates only 310KMac/pixel computation and 9.5M parameters, while in terms of performance, our method achieves a 20.7% BD-rate advantage over BPG on Kodak data, mirroring VVC's performance. Compared to other learned image compression algorithms with SOTA performance, our method has a great advantage in terms of computation/parameter count.
Model compression methods can reduce model complexity on the premise of maintaining acceptable performance, and thus promote the application of deep neural networks under resource constrained environments. Despite the...

This paper proposes the NeRI, an implicit neural representation (INR) based LiDAR point cloud compressor. In NeRI, we first transform a sequence of 3D LiDAR frames into a 2D range image sequence through range image projection over time. Then, we employ a neural network conditioned on the temporal frame index and associated LiDAR sensor pose to fit input range images as closely as possible. The optimized network parameters, which implicitly represent the input LiDAR data, are later lossily compressed. NeRI decoder is then initialized using decoded parameters to generate range images for reconstructing the 3D LiDAR sequence accordingly. Extensive experimental results demonstrate the significant superiority of NeRI regarding the compression efficiency and decoding speed compared to state-of-the-art 2D and 3D compressors for LiDAR point cloud.

This paper introduces a novel Dynamic Slope Detection (DSD) system for acquiring electrocardiogram (ECG) signals. DSD addresses the critical challenge of balancing data storage requirements with signal fidelity, particularly in resource-constrained environments like wearable devices. The system leverages the slope information of the ECG signal to guide efficient and adaptive data sampling. Validation using ten samples from the publicly available MIT-BIH Arrhythmia database confirmed significant data reduction compared to traditional sampling. The proposed method achieves a compression ratio of up to 12.5x while maintaining RR interval estimation error below +/- 0.1 msec.

Recent years have witnessed the prevailing progress of Generative Adversarial Networks (GANs) in image-toimage translation. However, the success of these GAN models hinges on ponderous computational costs and laborexpensive training data. Current efficient GAN learning techniques often fall into two orthogonal aspects: i) model slimming via reduced calculation costs;ii) data/labelefficient learning with fewer training data/labels. To combine the best of both worlds, we propose a new learning paradigm, Unified GAN compression (UGC), with a unified optimization objective to seamlessly prompt the synergy of model-efficient and label-efficient learning. UGC sets up semi-supervised-driven network architecture search and adaptive online semi-supervised distillation stages sequentially, which formulates a heterogeneous mutual learning scheme to obtain an architecture-flexible, label-efficient, and performance-excellent model. Extensive experiments demonstrate that UGC obtains state-of-the-art lightweight models even with less than 50% labels. UGC that compresses 40x MACs can achieve 21.43 FID on *** with 25% labels, which even outperforms the original model with 100% labels by 2.75 FID.
