Abstract: A scene is monitored by receiving image data representing a thermal image captured by a thermal image sensor (13) and a visual image captured by a visual image sensor (15), the thermal image and the visual image depicting a same view of the scene. Objects (9) are detected in the visual image and in the thermal image. A mask (17a) is defined in the view of the scene, and it is determined if an object (9) or an object part, inside the mask (17a), is present in both the thermal image and the visual image. If so, a modified mask (17b) is provided by excluding an area occupied by the object (9) or the object part from the mask (17a).

Abstract translation: 通过接收表示由热图像传感器（13）拍摄的热图像的图像数据和由视觉图像传感器（15）捕获的视觉图像来监视场景，热图像和视觉图像描绘场景的相同视图。 在视觉图像和热图像中检测物体（9）。 在场景的视野中限定掩模（17a），并且确定在热图像和视觉图像中是否存在掩模（17a）内的物体（9）或物体部分。 如果是这样，通过从掩模（17a）排除对象（9）或对象部分所占据的区域来提供修改的掩模（17b）。
