There is a belief that observers with color vision deficiencies (CVD) perform better in detecting camouflaged objects than normal observers. Some studies have concluded contradictory findings when studying the performance of normal and CVD observers in the camouflage detection tasks in different conditions. This work presents a literature review on this topic, dividing it into three different and contradictory types of results: better performance for CVD, for normal observers, or same performance. Besides, two psychophysical experiments have been designed and carried out in a calibrated computer monitor on both normal and CVD human observers to measure the searching times of the different types of observers needed to find camouflaged stimuli in two different types of stimuli. Results show the trend that, in our experimental conditions, normal observers need shorter searching times than CVD observers in finding camouflaged stimuli both in images of natural scenes and in images with synthetic stimuli.
有一种观点认为,色觉缺陷(CVD)观察者在探测伪装目标方面比正常观察者表现更好。一些研究在研究正常观察者和 CVD 观察者在不同条件下的伪装检测任务中的表现时得出了相互矛盾的结论。本文对这一主题进行了文献综述,将其分为三种不同且相互矛盾的结果类型:CVD 观察者表现更好、正常观察者表现更好或表现相同。此外,还设计并进行了两项心理物理学实验,在经过校准的计算机显示器上对正常和 CVD 人类观察者进行了实验,以测量不同类型观察者在两种不同类型刺激中找到伪装刺激所需的搜索时间。结果表明,在我们的实验条件下,正常观察者在寻找自然场景图像和合成刺激图像中的伪装刺激时,所需的搜索时间比 CVD 观察者短。
