摘要:

我们提出了一种算法,用于搜索图像集,使用手绘草图,描述多个对象的外观和相对位置。基于草图的图像检索(SBIR)方法主要匹配查询包含一个单一的,占主导地位的对象不变,其在图像中的位置。我们的工作利用图纸作为一个简洁和直观的表示指定整个场景组成。我们训练一个卷积神经网络(CNN)来编码草图对象中被掩盖的视觉特征,将这些特征汇集到一个空间描述符中,对构图中对象的空间关系和外观进行编码。将CNN骨干训练为在三元组损失下的连体网络产生用于测量组成相似性的度量搜索嵌入,其可以通过应用乘积量化来有效地用于视觉搜索。

英文摘要:

We present an algorithm for searching image collections using free-hand sketches that describe the appearance and relative positions of multiple objects. Sketch based image retrieval (SBIR) methods predominantly match queries containing a single, dominant object invariant to its position within an image. Our work exploits drawings as a concise and intuitive representation for specifying entire scene compositions. We train a convolutional neural network (CNN) to encode masked visual features from sketched objects, pooling these into a spatial descriptor encoding the spatial relationships and appearances of objects in the composition. Training the CNN backbone as a Siamese network under triplet loss yields a metric search embedding for measuring compositional similarity which may be efficiently leveraged for visual search by applying product quantization.
