Applications Of Denoising For The Image Of Hand And Wrist In Frequency Domain In The System Of Bone-Age Assessment Without Film

In the research of pedology and physical training,bone age plays an important role. In the past, people who evaluate obtain with the aid of film image grade of bone score,then work out the bone age,which makes efficiency too low to satisfy the requirement of the handling of real time,and cause a large amount of the consuming. The system of bone age assessment without film is put forward under this background.This system is still based on The Standard of Estimating Skeletal Maturity for Chinese (Method of CHN Scoring).It is a joint production of iatrology and technology of image processing,etc.The article will put forward a kind of new denoising method of digital image in frequency domain:start with a series of Fourier Transforms on hand and wrist X-ray image; then carry on single frame mean value to deal with;finally,carry out the single frame smooth handling of frame frequency .One that is through steps the above treated,get better test result,improve the artificial accuracy that read.
