Abstract	本发明公开了一种相似图像检索方法、系统、设备及存储介质，本方法将待测试缺损绘画图像输入至预设的语义修复模型中，获得预设的语义修复模型输出的粗修复绘画图像；提取粗修复绘画图像中多个尺度的像素神经特征和像素RGB特征；根据多个尺度的像素神经特征和像素RGB特征，获取第一预设数量的相似像素；验证第一预设数量的相似像素的空间一致性，选取第二预设数量的空间一致的特征匹配对；根据特征匹配对，计算粗修复绘画图像与其他绘画图像之间的密集对应关系，并根据密集对应关系进行相似图像检索，获得与粗修复绘画图像相似的相似绘画图像。本发明能够提高相似图像检索的准确率。
Other Abstract	The invention discloses a similar image retrieval method, system and device and a storage medium, and the method comprises the steps: inputting a to-be-tested defective drawing image into a preset semantic restoration model, and obtaining a coarse restoration drawing image outputted by the preset semantic restoration model; extracting pixel neural features and pixel RGB features of a plurality of scales in the coarse restoration drawing image; obtaining a first preset number of similar pixels according to the pixel neural features and the pixel RGB features of the multiple scales; verifying the spatial consistency of the first preset number of similar pixels, and selecting a second preset number of feature matching pairs with the spatial consistency; and according to the feature matching pair, calculating a dense corresponding relationship between the coarse repair drawing image and other drawing images, and according to the dense corresponding relationship, carrying out similar image retrieval to obtain a similar drawing image similar to the coarse repair drawing image. According to the method, the similar image retrieval accuracy can be improved.
