Image retrieval method based on image principal part detection
摘要
Abstract
Aimed at the problem-poor result of image retrieval arising from the complexity of image background,a kind of image retrieval method combined with subject detection was put forward.This method has initially trained the deep Convolutional Neural Network (CNN) model used in object detection and used the model detection well trained to inquiry the object class,class probability and the coordinate and feature of region where it was placed in the image.After the image subject estimated in accordance with the object's class probability and coordinate of region where it was placed,the image similar to the subject in the database was found.The cosine distance of region feature between the image inquired and similar image retrieved was caculated,combined with the class probability to carry out grading and sorting for all images retrieved and returned the top 10 images with the highest scores to be as the retrieved result.Finally verification of algorithm was conducted on VCO2007 dataset and paper dataset collected by myself.The experiment result shows that the total accuracy for retrieved result of 1 000 test images is 96.5 %,which has raised 6.6 percent points than the existing method.The proposed method can effectively exclude the disturbance of image background and get more accurate retrieved result and location accuracy.关键词
