“…The LED light source emitted to the area is capable of detecting the surface for sample. On the other hand, there are four kinds of spot non-uniformity defects on the green layer to be evaluated, labelled as A1, A2, B1, and B2 in Figure 5 [4]. Both A1 and A2 are the samples with artificial defects at 20 mm in diameter, which are a dark region and a low transparency with thick film.…”

“…The acceptable level of difference (∆E), between the measured colour and the true colour is calculated as the square root of the combined difference between the L*, a*, b* of the measured colour and the true colour, where true colour is defined as the average colour that would be obtained after taking an infinite amount of measurements [11]. Limiting the colour difference to one ∆E is sufficient for sorting meat into quality grades, since one ∆E is the limit for humans when it comes to detecting a colour difference [40,41]. Where the intended use of the colour data is for indications of microbial load, or other shelf-life traits, then a smaller ∆E could be required [42].…”

“…Currently, liquid crystal (LC) flat panel displays (FPDs) are moving toward high-imaging resolution, quick in-plane switches, vivid colour, saving energy, and low radiation [1,2]. For example, image resolution is advancing from high definition (HD) to ultra-high definition (UHD), i.e., from 2 K (1920 × 1080 pixels), to 4 K (3840 × 2160 pixels), 8 K (7680 × 4320 pixels), 16 K (15,360 × 8640 pixels), and even beyond to 32 K (30,720 × 17,280 pixels) [3]. Thus, full high-resolution images for enriching the stereoscopic visibility of the FPDs can be achieved [4,5].…”
