MINC (Materials in Context Database)

MINC 比以前的材料数据库大一个数量级，同时在其 23 个类别中更加多样化和良好采样。使用 MINC，我们为两个任务训练卷积神经网络 (CNN)：从补丁中分类材料，以及在完整图像中同时识别和分割材料。对于 MINC 上基于补丁的分类，我们发现性能最好的 CNN 架构可以达到 85.2% 的平均分类准确率。我们将这些经过训练的 CNN 分类器转换为一个高效的全卷积框架，并结合全连接条件随机场 (CRF) 来预测图像中每个像素的材料，实现 73.1% 的平均类准确率。我们的实验表明，拥有像 MINC 这样的大型、良好采样的数据集对于现实世界的材料识别和分割至关重要。MINC is an order of magnitude larger than prior material databases, while being more diverse and better-sampled across its 23 categories. Using MINC, we trained convolutional neural networks (CNNs) for two tasks: classifying materials from image patches, and simultaneously identifying and segmenting materials in full images. For patch-based classification on MINC, we found that the best-performing CNN architectures achieve an average classification accuracy of 85.2%. We converted these trained CNN classifiers into an efficient fully convolutional framework, combined with fully connected conditional random fields (CRFs) to predict material labels for each pixel in an image, achieving an average per-class accuracy of 73.1%. Our experiments demonstrate that large, well-sampled datasets like MINC are critical for real-world material recognition and segmentation.
