 # Infrared-Small-Target-A
 Here, we shared a infrared small target dataset and we wish it could be valuable for researchers all over the world.
-It may involve in some military application, but we wish it can be beneficial to some civilian use such as UAV or bird alarming in airports, birds migration monitoring or something else.
+It may involve in some military application, but we wish it can be beneficial to some civilian use such as UAV or bird alarming in airports, birds migration monitoring or something else. We name this dataset as 'infrared small target-A ' dateset, simplified as 'IST-A' dataset.
 
 Images in training dataset or test dataset are picked out from 72 image sequences in a sequencial traversal style. The total number of orginal images is over 22K, but only 10117 training images and 2476 test image are picked out. For each sequence, only when the index of current traversal image is 25 larger than the index of last valid image or the SSIM between current traversal image and last valid image is smaller than 0.99 will be current traversal image treated as a valid image. The valid images will be randomly distributed to training dataset or test dataset. Of course, the first image in each sequence will be treated as a valid image so the traversal processing can be implemented.
