The result.zip contains the groundtruth data of ¡°direct ground truth labeling¡±. According to our paper, we provide a pre-selected query samples list to every annotator. The annotator can labels his/her own selected images set, which is similar to the query sample based on his/her own visual perception. Consequently, after such process, for each query sample, there is a corresponding image list in which the image is similar to the query based on human perception and thus the list could be considered as the retrieval groundtruth. 7 college students evolve in this annotation work. The result is build based on the average of 7 students¡¯ annotation results. So, you can get the annotation result as the following: 1. Download the file result.zip 2. Unzip the file to get resultnew.txt The format of this file is the following: The location of Query image 1 at Corel Image Gallery 1 Million The Number of The result Images for Query 1 The location of Result Image 1 Similarity to the Query([0,1]) The location of Result Image 2 Similarity to the Query([0,1]) ¡­ The location of Query image 2 The Number of The result Images for Query 2 The location of Result Image 1 Similarity to the Query([0,1]) The location of Result Image 2 Similarity to the Query([0,1]) ¡­ For example, Disk08/Photos/Mosaic/639005.JPG ( Query Image¡¯s location ) 146 ( number of its ground truth result ) Disk08/Photos/Mosaic/639059.JPG ( Location of the 1st result ) 1.000000 ( Similarity of the 1st result ) Disk08/Photos/Mosaic/639069.JPG ( Location of the 2nd result ) 1.000000 ( Similarity of the 2nd result ) ¡­ ¡­
