This page contains the test images that we used for our Wallflower paper.* We tested several different background maintenance algorithms on seven different image sequences. For each test image in the sequence, the output of the algorithm was an image segmented into background and foreground pixels.
Each of the seven different test sequences represents a different, potentially problematic scenario for background maintenance. In general we used the first 100 images in each sequence for training. We then ran each algorithm on the remainder of the sequence up to a prespecified evaluation image. We compared the algorithm's result on the evaluation image to a hand-segmented version of the evaluation image.
We have created one .zip file for each of the seven test scenarios. Each .zip file contains the training images, test images, and hand-segmented evaluation image for comparison, all in BMP format. Each .zip file also contains a file called "script.txt" that gives a short description of the events in the sequence and specifies which images are used for training, testing, and evaluation.
The table below shows sample images and gives links to the ftp site with the .zip files.

本頁包含我們Wallflower paper的測試圖片。我們對七種不同的圖像序列測試了幾個不同的背景維護算法。對於每一個測試圖像序列，該算法的輸出是一個被分割的圖像前景和背景。
七個不同的測試序列中每一個都代表一個背景維護算法中不同的，有潛在的問題的場景。一般，我們用前100幅圖像序列來進行訓練，而用剩餘的圖像序列來進行評估。我們將評估的圖像和手動分割圖像進行了比較。
我們已經對七個測試場景中的每一個創建了zip文件。每個zip文件包含訓練圖像，測試圖像以及手動分割的評價圖像，所有都是BMP格式。每個zip文件還包含一個“script.txt”文件，具體說明哪些圖像序列用來訓練，測試，評價。
下表顯示樣本圖像和給的FTP站點鏈接zip文件。
