回声图用于可视化渔业声学数据,但颜色图的选择对外观有显着影响。定量回声图应使用彩色图,彩色图是彩色的(具有可感知的颜色种类和强度),连续的(具有单调的亮度),和感知均匀的(在其范围内具有感知颜色对比度的一致性)。我们使用近似感知均匀的颜色空间(CIELAB)来衡量颜色图是否是彩色的(),顺序的()和感知均匀的(ρ= 1)。虽然测试的所有渔业声学彩色地图都是彩色的,但没有一个是连续的或感觉上均匀的。广泛使用的EK500彩色地图色彩丰富(),而不是连续的(),并且在其范围内具有高度不均匀的感知对比度()。在所测试的渔业声学彩色地图中,大规模调查系统的默认彩色地图色彩最少(),但最接近于连续()和感知均匀()。现代彩色地图是专门为色彩对比一致性、红绿色盲观众的可访问性和单色印刷时的易读性而设计的,可能更适合于定量渔业声学回声图的介绍和解释。
Echograms are used to visualize fisheries acoustic data, but choice of colour map has a significant effect on appearance. Quantitative echograms should use colour maps, which are colourful (have a perceived variety and intensity of colours), sequential (have monotonic lightness), and perceptually uniform (have consistency of perceived colour contrast over their range). We measure whether colour maps are colourful (), sequential (), and perceptually uniform (ρ= 1) using an approximately perceptually uniform colour space (CIELAB). Whilst all the fisheries acoustic colour maps tested are colourful, none is sequential or perceptually uniform. The widely usedEK500colour map is extremely colourful (), not sequential (), and has highly uneven perceptual contrast over its range (). Of the fisheries acoustic colour maps tested, the Large Scale Survey System default colour map is least colourful (), but comes closest to being sequential (), and perceptually uniform (). Modern colour maps have been specifically designed for colour contrast consistency, accessibility for viewers with red-green colour-blindness, and legibility when printed in monochrome, and may be better suited to the presentation and interpretation of quantitative fisheries acoustic echograms.
