The paper presents the evaluation and grading of different techniques that are in use today for the de-interlacing of High Definition interlaced content. S2 (1080i/25) is one of the standards for High Definition Television (HDTV) that is broadcasted in Europe, USA and other parts of world. Different de-interlacing techniques starting from basic ones like line averaging, field insertion to advanced ones like motion adaptive and motion compensation are reviewed. These techniques are evaluated using objective video quality metrics like Peak Signal to Noise Ratio (PSNR), Mean Square Error (MSE) and more advanced one like Structural Similarity (SSIM). Subjective evaluation is carried out using perception based subjective video quality metric (Mean Opinion Score). The comparison of subjective and objective results shows that there is a high correlation among the subjective scores and the objective criterion.
