for the age range of 0-2 years of age. Early Speech Perception Test (ESPT) : Environmental speech perception test was developed by Jean S Moog and Ann E Geers in the year 1990 for the children between the age range of 3-12 years. This test establishes objectives for auditory training for children who are profoundly hearing impaired. It helps in measuring affects of auditory training and effectiveness of hearing aids or cochlear implants. Meaningful Auditory Integration Scale
The scale ranges from grade 0 to grade 4, with a grade of 4 being the most severe. Grade 0 indicates there are no radiologic osteoarthritis features. Grade 1 severity shows minimal osteophyte formation. Grade 2 shows definite osteophyte formation without impaired joint space. Grade 3 indicates there is a moderately decreased joint space, and grade 4 shows a severely impaired joint space with sclerosis of the underlying bone
take only two values i.e. maximum and minimum in the dynamic range, giving the appearance of dark spots in the white region and white spots in the dark region of an image while the unaffected region remain unchanged. For an 8 bit image the range is 0 and 255.Salt-and-pepper noise with variance 0.03 is shown in the Figure 1.1. Figure 1.1: Salt-and Pepper noise (b) Gaussian Noise Gaussian noise is a statistical noise which is evenly distributed over the image. The Gaussian noise has probability
