An image with good contrast has sharp differences between black and white, and this helps us to label ground truth data since we can find the edge of objects clearly.
However, the image we want to label on may have poor contrast. For example, medical image is a high dynamic range image in many cases, and intensity values tend to be limited to specific portion of the range.

This tool enable you to interactively adjust contrast and brightness for pixel labeling. You can adjust contrast and brightness by changing image window width and window center on separately launched figure window from Labeler App.
This tool can be used with imageLabeler, videoLabeler and groundTruthLabeler. Please see the header of adjustContrast.m to learn how to use this tool.

医療画像等、特にダイナミックレンジの広い画像データにおいては、明部と暗部の差がそれほど大きくない場合があり、
オブジェクト境界部分のラベリング精度が荒くなる場合があります。
本ツールでは対話的にコントラストやブライトネスを調整可能とする機能を提供し、ラベリング作業を支援します。
imageLabeler, videoLabeler や groundTruthLabelerで提供されている自動ラベリング機能の一部として、
インポートして利用します。利用方法についてはmファイルのヘッダ部分をご覧ください。
