In this paper, we propose a compression algorithm that reduces color bits according to importance by using YUV color space among various methods of compressing image data. 4: 2: 2 subsampling is the standard in the field of video. By using the color information and the characteristics of the human retina, YUV color data was reduced by 4: 2: 2 subsampling. YUV and RGB can be converted to each other by using the following transformation matrix. The image data is converted into color space by YUV, and the relatively low U and V bits are subjected to the downscaling operation, and then the data is compressed through 4: 2: 2 subsampling. The performance of the proposed algorithm is compared and analyzed through comparison with existing methods. As a result of the analysis, it was possible to compress the image without reducing the information of the low importance color element and without a significant deterioration in the quality compared with the original.

The CT urography is a non-invasive, essential examination for patients who have a urinary system disease. Maximizing the opacification and distention of the bladder is important because it facilitates the detection of tumors and provides morphological information on the bladder. This study evaluates the difference in the quality of the bladder filling image and the total dose of radiation exposed to patients when the repositioned patient, after having rolled over, is not rescanned in the scout phase before proceeding to be scanned in the excretory phase. The CT urography protocols are divided into two groups, In Group A, the patient is scanned twice in the scout phase, first in the supine position and then again in the prone position after being repositioned on the CT table. In Group B, the patient is scanned only once in the scout phase in the prone position before being repositioned. In the quantitative evaluation of the two groups, Group B had lower average standard deviation of the CT number in the bladder than Group A (p<0.05). In the qualitative and total dose evaluation of the two groups, Group B had higher value than Group A (p<0.05). This study demonstrates that it is possible to get a homogeneous image of the bladder by not rescanning the patient after being repositioned.

보물로 지정되어 있는 남명천화상송증도가(南明泉和尙頌證道歌)의 삼성본(三省本: 보 물 제 758-1호)과 공인본(空印本: 보물 제758-2호)의 사진 이미지를 비교 분석하여 두 판본 간의 차이점을 조사하였다. 공인본의 보물지정 당시인 2012년의 보고서에 따르면 두 개의 판본은 모두 같은 판에서 인출된 것이며 공인본이 삼성본보다 후쇄본으로 추정된다고 한다. 두 개의 판본은 구성, 광곽의 형태, 글자체에 이르기까지 매우 유사하여 육안에 의한 확인만으로는 그 차이를 구별하기 쉽지 않아 전문가들의 주관적의 의견을 수렴하여 결론을 도출한 것으로 추정 된다. 본 연구에서는 이미지 분석을 통하여 각각의 판본상에 나타난 인쇄특징을 바탕으로 인출 시기의 전후관계 및 동일한 판에서 인쇄된 것인지 아니면 서로 다른 판에서 인쇄된 것인지 판단할 수 있는 근거자료를 수집하여 정리하였다. 면밀한 이미지 비교와 분석의 결과, 삼성본과 공인본은 서로 다른 판에서 인출된 것이며 인출시기도 공인본이 삼성본에 비해서 후쇄본이라 는 보고서의 내용도 수긍하기 어렵다는 결론에 도달하였다. 또한 삼성본에서 볼 수 있는 목판 인쇄의 특징과는 사뭇 다른 특징들이 관찰되어 공인본의 인출에 사용된 인쇄기술 및 인출시기 에 관한 추가조사 및 후속연구가 필요할 것으로 보인다.

Photographic images of the Samseong-version (三省本: Korea’s Treasure No. 758-1) and the Gongin-version (空印本: Korea’s Treasure No. 758-2) of Nammyeongcheon Hwasangsong Jeungdoga (南明泉和尙頌證道歌: Nanmingquan Song Zhengdaoge) were compared and analyzed to investigate the differences between the two versions. According to a report in 2012 at the time of the designation of the Gongin-version as Korea’s treasure, both versions were printed from the same woodblocks. The Gongin-version is presumed to be a later print than the Samseong-version. The two versions are very similar in format and shape of border lines and characters. It is difficult to determine the differences with the naked eye, even for experts. In this study, based on the printing characteristics observed from each version through image analysis, useful evidence to determine whether it was printed using the same or different woodblocks and the order of printing was collected. As a result of careful image comparison and analysis, we concluded that the Samseong- and the Gongin-version were printed from different woodblocks, or possibly different typesetting. It was difficult to agree with the content of the report that the Gongin-version was a later print than the Samseong-version. In addition, it was noted that the Gongin-version print has characteristics quite different from the typical characteristics of woodblock printing seen in the Samseong-version. Additional investigations and follow-up studies on the printing technology used for Gongin-version print and the timing of printing are recommended.

This paper describes the IT convergence system using a difference image, an erosion operation and a mobile application for the measurement of the dripping speed of the medical liquid in a drip chamber, which can estimate the remaining time using image processing from video frame information based on Android technology. The video frames were first made using a smartphone camera and we calculated the difference image between the n image and the (n+1) image and then changed into binary images using the threshold value. At this point, it is very important to find an optimal threshold value to recognize the dripping of the liquids. After that, we applied the erosion operation with threshold to detect the handshaking error of the smartphone camera. As a result, the user can adjust the dripping speed according to the doctor’s prescription, exactly like watching the progress bar of a mobile application. The experiment results show that our method using image processing technique accurately measures the dripping speed for a wide range of speeds that are sufficient for ordinary practice.

According to the color difference fabric dyeing measurement in production, partial color existed bad real-time problems. Color difference and color of RGB fabric images put forward by using the method of color distribution measurement of general, which needed rapid measurement of large area color. According to RGB distribution histogram of the image, the measured color with sample color similarity and distribution curve of characteristic value was calculated, obtained the RGB color model, and gives a method of a partial color judging. The experiment proves the feasibility of this measurement fabric color difference and the judgment method and effectiveness of partial color. Color cast detection method has overcome the limitations of the traditional methods of detecting image color cast. In order to partial color image detection is performed after correction, using a combination of gray world and a perfect reflection of the color correction method, to make up for the shortcomings of traditional method. The experimental results show that, the color deviation correction method of image analysis based on detection improved the reliability of color cast detection. The method uses characteristics of image analysis, it has universal applicability.

A method for image compression, adaptive difference compensation vector quantization using dynamic image block adjustment is proposed in this paper. Before image coding, this proposed method analyzes the similarity values between the encoding image sub-block and its 8-neighbor sub-blocks, then determines the encoding rule according to the similarity value and the preset threshold. If the similarity value is approximate to the threshold, we use the same codeword to encode the neighbor block and the encoding image block; otherwise, the neighbor block is separately encode. When encoding, the difference between each image block and its matching codeword is first computed to obtain the difference image, and then the sign bits of the pixel difference is imposed the running length coding on and attached after the codeword index. When decoding, this proposed method restores the compressed image according to the codeword index, performs the running length encoding to deal with decode the attached information, uses the window of 33 size to tackle the adaptive difference compensation and derive the final decoding image. The experiment results reveal that this proposed method can improve the encoding speed and image restoration performance against the normal vector quantization.

Motion blur of image is caused by relative motion between camera and photographed object during protographing. Motion-blurred image restoration is an important part of the image restoration. Image restoration is the process of recovering original image from its degraded version. This paper focuses on image restoration blurred by uniform linear motion. Principle of image restoration technique is introduced. Degradation model and blurred model of horizontal motion are analyzed. Two methods to solve image restoration caused by uniform linear motion are described in detail: Wiener filter in frequency domain and difference method in spatial domain. Comparisons are made between spatial method and the method in frequency domain. Experimental results on test image show that the spatial difference technique has better performance than the method based on Wiener filter.

Reversible data hiding, which can recover the original image without any distortion after the extraction of the hidden data, has drawn considerable attention in recent years. However, the previous researches of histogram based data hiding scheme share the problem of the limit of the embedding capacity of secret data because they use bit level data processing. To overcome the problem, we propose a new twice level block-based reversible data hiding scheme using difference image histogram. The proposed scheme uses block-based inverse S-order image histogram and allows for dual-level data hiding to increase the hiding capacity. The simulation results demonstrate that the proposed scheme generates good performance in the embedding capacity.
