This contribution evaluates the impact of chroma subsampling using two different downsampling filters using objective metric. Objective results show that distributing 4:4:4 is more efficient than its 4:2:0 counterpart for medium to high bit-rates. For low bit-rates, this increase in efficiency is reduced and in some cases even reversed.

Magnesium (Mg) has the lowest density of all structural metals and excellent potential for wide use in applications. While pure Mg inferior mechanical properties; addition further elements at various concentrations produced alloys with enhanced performance corrosion resistance. An important consequence adding such is that saturated matrix can locally decompose to form solute clusters intermetal...
