iMaterialist Challenge at FGVC 2017 FGVC 2017的iMaterialist挑战

当购物者在线上购物时，实现自动检测照片中的商品属性是一个梦想成真。但是，自动产品识别很难，因为对于同一产品，可以在不同的照明，角度，背景和遮挡级别下拍摄照片。同时，不同的细粒度属性标签可能看起来非常相似，例如，宝蓝色与绿松石色。当今许多通用识别机根本无法感知照片之间的细微差别。

解决此类问题的原因是为什么计算机视觉和模式识别会议（CVPR）专门针对数据科学家举办了专门针对细粒度视觉分类的研讨会，称为FGVC4研讨会。作为此次研讨会的一部分，CVPR与Google合作，挑战数据科学界，以帮助推动自动图像分类的最新发展

Automatically detecting product attributes in photos has long been a highly sought-after goal for online shoppers. However, automated product recognition is a challenging task, as images of the same product can be captured under varying lighting conditions, viewing angles, backgrounds, and occlusion levels. Meanwhile, distinct fine-grained attribute labels can appear highly similar—for example, sapphire blue versus turquoise. Many current general-purpose recognition models simply fail to capture the subtle differences between such images. To address these challenging issues, the Conference on Computer Vision and Pattern Recognition (CVPR) organized a specialized workshop on fine-grained visual classification, dubbed FGVC4, targeted specifically at data scientists. As part of this workshop, CVPR partnered with Google to challenge the data science community to advance the state-of-the-art in automated image classification.
