Question

The paper is titled "Soil transference patterns on bras: Image processing and laboratory dragging experiments"

Read the following paper Murray et al., Forensic Science International, 258 (2016) 88-100 Questions: 1. In the section 2.2.2, why is it important that the authors mention that the Munsel soil color was "recorded by naked eye in natural daylight"? (1 point) 2. In Figure 6, give the hue, value and chroma for the four colors chosen by the naked eye. (2 points) Why is the value lower for wet soils than dry soils? (1 point) 3. In the conclusion section, why do the authors propose that a "scale bar with a white color standard" would assist for calibration and improve recognition? (1 point)

Explanation / Answer

1. Colours will be clearly visible and distinguishable if we observe with naked eye. If we use any lens, that may effectbthe final color conclusion. Because factors like glare, reflection or the material of the devive we use may give us a false assumption of colour. And a color has to be observed obviously in day light. Because visible light colors and their shades are visible in day light. You can see red color as red in visible light but not in dark. It is as simple as.such.

2.

1. Hue- 7.5YR, value-5, chroma-2

2. 7.5YR, 3,2

3. 7.5YR, 5, 2

4. 7.5YR, 3, 2

3. Because white color scatters all incident light completely. It ideally reflects respective colours and hence no dissimilarities occur
