【One-Line Pitch】 A curated 2024 journal issue mapping how visual perception AI is moving from lab benchmarks to deployable systems—covering high-definition maps for autonomous driving, fine-grained image understanding, model reuse, and medical diagnosis. Best for engineers, researchers, and technical decision-makers who want a cross-section of applied computer vision rather than a single-topic tutorial. 【Book Arc】 - **Opening (~0%–10%)**: The issue frames its theme—"visual perception"—and previews four threads: HD map construction, fine-grained image perception and its security, visual deep-model "refining/recombination" (炼知), and intelligent pathology diagnosis. It also signals a broader argument that AI is reshaping traditional industry. - **Early (~10%–30%)**: Two foundational surveys run in parallel. One traces HD map construction for autonomous driving from offline annotation toward online semantic and vectorized maps. The other builds up fine-grained image recognition and image captioning, then pivots to the security threats (adversarial and backdoor attacks) these perception models face. - **Middle (~30%–50%)**: The focus shifts to model efficiency and reuse. The "visual deep-model refining" article lays out homogeneous and heterogeneous model recombination, knowledge distillation, pruning, and data-free recombination—essentially how to build compact custom models from existing trained ones. - **Late (~50%–70%)**: Attention turns to large visual models and parameter-efficient fine-tuning, plus a survey of lower-limb exoskeleton gait-recognition systems—showing perception techniques reaching beyond standard vision tasks. - **Ending (~70%–100%)**: The closing sections move to application and governance: a case-and-fuzzy-reasoning method for urinary system inflammation diagnosis, a legal discussion of "safe harbor" rules for generative AI, and a piece on generative AI's value and risks in higher education. 【Key Takeaways】 - **HD maps are shifting from offline annotation to online generation** (Early): the issue contrasts expensive, slow manual HD maps with online semantic and vectorized maps built from multi-camera and LiDAR data, arguing the future lies in real-time, cloud-shared map updates. - **3D scene understanding is the bottleneck for online mapping** (Early): deep-learning methods work in principle but struggle with annotation cost, real-time constraints, and recognizing objects unseen in training—so practical solutions must balance accuracy, latency, and training expense. - **Fine-grained recognition hinges on discriminative regions and features** (Early): the survey walks from part-based localization-classification networks to weakly supervised and attention-based methods, showing how the field reduced its dependence on costly part or bounding-box annotations. - **Image captioning evolved from detection-description pipelines to one-stage, pretrained vision-language models** (Early): Transformer architectures and large-scale pretraining progressively improved entity-relation modeling and global context handling. - **Perception models face real security threats** (Early): adversarial attacks (white-box and black-box) and backdoor attacks (data-poisoning and non-poisoning) can cause misclassification, with defenses grouped into preprocessing, suppression, and detection/purification. - **Model "refining" reframes training as knowledge reuse** (Middle): instead of "big data + big labels + big model," the approach recombines existing trained models into compact, task-specific students—protecting data privacy and lowering customization cost. - **Recombination spans homogeneous and heterogeneous models** (Middle): techniques include layer-wise fusion, common feature learning, knowledge distillation, automated pruning, and data-free recombination when training data is inaccessible. - **The issue closes on application and governance, not just technique** (Ending): medical diagnosis, exoskeleton gait recognition, generative-AI legal rules, and higher-education policy round out the picture. 【Reading Tips】 - **Skim the opening table of contents first** to pick your thread; the issue is a collection, not a single narrative, so reading cover-to-cover is optional. - **Deep-read the HD map and fine-grained perception surveys** if you work in autonomous driving or vision security—they carry the most technical density. - **Treat the model-refining article as a methods catalog**: focus on the four research directions and the distillation/pruning techniques rather than every equation. - **Read the closing governance and education pieces as context**, not engineering guidance—they frame where the technology is heading socially and legally. - **Use the reference lists as a reading map**; the excerpts show extensive citations to CVPR, ICCV, and NeurIPS work worth following up. 【Coverage Limits】 This guide is based on stratified excerpts covering the issue's opening, early, middle, and closing sections; some articles (e.g., parameter-efficient fine-tuning, exoskeleton gait recognition) appear mainly through titles and brief mentions, so their detailed content is not fully represented here.
