“…Penelitian ini melakukan perbandingan dan analisis pada kelima metode pendeteksian tepi yang berupa operator Sobel, operator Prewitt, operator Laplace, operator Laplacian of Gaussian (LoG) dan operator Kirsch dengan menggunakan permograman MATLAB. Perbandingan yang dilakukan pada penelitian ini bertujuan untuk membandingkan kualitas dari masingmasing operator deteksi tepi menggunakan penilaian objektif, hal ini diperlukan karena menghasilkan pengukuran yang standar, cepat dan mudah [15]. Pengukuran lainnya dapat menggunakan pengukuran kualitas citra secara subjektif (indera manusia), hal ini dapat dilakukan untuk menilai kualitas citra, namun hal tersebut sangat sulit dilakukan karena kondisi penilaian harus tergantung pada penglihatan manusia [16][17].…”

Identification of object boundaries in a digital image is developing rapidly in line with advances in computer technology for image processing. Edge detection becomes important because humans in recognizing the object of an image will pay attention to the edges contained in the image. Edge detection of an image is done because the edge of the object in the image contains very important information, the information obtained can be either size or shape. The edge detection method used in this study is Sobel operator, Prewitt operator, Laplace operator, Laplacian of Gaussian (LoG) operator and Kirsch operator which are compared and analyzed in the five methods. The results of the comparison show that the clear margins are the Sobel, Prewitt and Kirsch operators, with PSNR calculations that produce values above 30 dB. Laplace and LoG operators only have an average PSNR value below 30 dB. Other quality comparisons use the histogram value and the contrast value with the highest value results in the Laplace and LoG operators with an average histogram value of 110 and a contrast value of 24. The lowest histogram and contrast value are owned by the Sobel and Prewitt operators.

“…In order to improve the accuracy of the image quality evaluation model with subjective and objective uniformity, Watson Just Noticeable Difference (JND) model is introduced, the corresponding relation between ITU-R quality and impairment scales model and objective assessment by JND model is built [6]. The following empirical mapping is the function between the JND objective index and the evaluation grade for the case of gray image.…”

“…Following this approach, an improved estimation of the JND in terms of luminance and contrast masking can be obtained literatures [5]. In [6], we built the corresponding relation between subjective evaluation criteria and objective assessment by JND model. However, with the objective measures of SHSIM and JND, we can also note that the deviation of the subjective value and objective value.…”

Abstract. Image quality evaluation standard mainly relied on the traditional standard like peak signal to noise ratio (PSNR), but PSNR does not meet people's subjective assessment. To obtain more accurate evaluation with subjective and objective uniformity, the multi-indexes are considered. Our evaluation system includes three parts: (1) grade evaluation; (2) auxiliary evaluation; (3) reference evaluation. The value of grade evaluation is mainly determined by the grade evaluation, and minor modifications are made by the auxiliary evaluation. The reference evaluation provides the traditional objective standards so as to comparative analysis. The results of actual operation show that it is comprehensive and effective.
