본 논문은 영상에서 형태적 정보를 추출하는데 사용되는 수학적 형태학(mathematical morphology)에 퍼지 집합 이론을 적용하여 새로운 퍼지 수학적 형태학을 제안한다. 일반적인 수학적 형태학은 이진 영상에만 적용되는 한계를 가지고 있었다. 이를 그레이 스케일 영상에도 적용 가능하도록 한 Sinha와 Dougherty[8]이 제안한 방법도 기하학적 형태 변환을 보장하지 못하는 결점이 있었는데 본 논문에서는 그 결점을 제거하는 새로운 수축(erosion)과 확장(dilation) 연산을 정의하고 그 특성을 연구하였다. 본 논문이 제안한 방법과 [8]의 방법을 실제 영상에 대한 실험으로 비교하였다.

This paper presents efficient real time software implementation methods for the grayscale morphological composite function processing (FP) system. The proposed method is based on a matrix representation of the composite FP system using a basis matrix composed of structuring elements. We propose a procedure to derive the basis matrix for composite FP systems with any grayscale structuring element (GSE). It is shown that composite FP operations including morphological opening and closing are more efficiently accomplished by a local matrix operation with the basis matrix rather than cascade operations, eliminating delays and requiring less memory storage. In the second part of this paper, a VLSI implementation architecture for grayscale morphological operators is presented. The proposed implementation architecture employs a bit-serial approach which allows grayscale morphological operations to be decomposed into bit-level binary operation unit for the p-bit grayscale singnal. It is shown that this realization is simple and modular structure and thus is suitable for VLSI implementation.

The effect of processing conditions on the morphology of polyphenyleneoxide (PPO)/polyamide 6 (PA 6) blends were investigated. Injection molded part with a $15cm{\times}15cm{\times}3.2mm$ sized plate was molded with various injection molding conditions, and the morphology of the injection molded blends was investigation by using SEM. As a result, we found that molded part shows very complicated morphology because it has experienced complex thermal, shear and elongation history during the processing.

This paper is proposed the wavelet morphology algorithm with the spatial auto-object segmentation concept and the clustering concept. When it is segmented the color face by using the proposed algorithm, it is made to the simple image. Also, it is used the spatial quality in order to segment and detect the image as a real time without the user's manufacturing. This removed a small part that is regarded as a noise in image by HSV color model and applied the wavelet morphology to remove a part excepting for the face image. In this paper, it is made a comparison between the wavelet morphology algorithm and the morphology algorithm. And It is showed to accurately detect the face object parts in the image appled to HSV color space model.

Low frequency noise components causes the baseline drift in the ECG signals. In this paper, a morphological operation and smoothing spline technique are used for ECG signal processing in order to accomplish baseline correction. Removing the baseline drift from ECG signal using morphology operation, the feature of original signal may be distorted. To resolve this distortion problem, we applied a smoothing spline operation after morphology operation. In order to compare with existing morphology operation method for baseline correction, we apply proposed method to ECG data in MIT/BIH database. Compared to other existing method, our proposed method achieved low data distortion on the original signal.

This paper presents a method for determining optimal grayscale function processing(FP) morphological filters under the least square (LMS) error criterion. The optimal erosion and dilation filters with a grayscale structuring element(GSE) are determined by minimizing the mean square error (MSE) between the desired signal and the filter output. It is shown that convergence of the erosion and dilation filters can be achieved by a proper choice of the step size parameter of the LMS algorithm. In an attempt to determine optimal closing and opening filters, a matrix representation of both opening and closing with a basis matrix is proposed. With this representation, opening and closing are accomplished by a local matrix operation rather than cascade operations. The LMS and back-propagation algorithm are utilzed for obtaining the optimal basis matrix for closing and opening. Some results of optimal morphological filters applied to 2-D images are presented.

Morphometric analysis of Lycorma delicatula was performed to confirm whether local individuals had a geographical difference in their wing variations. The L. delicatula individuals were collected from 10 localities in Korea, China, and Japan, and 14 morphometric characteristics selected from the forewing were analyzed. The Korean individuals were similar to the ones from the northern area of the Yangtze River, but less similar to the others from the southern area of the Yangtze River. The individuals from Seoul and Buan were very similar to those from Shanghai. In case of wing spots, the individuals from Beijing had relatively small spots, while the ones from Linan had big spots. The Japanese individuals had a relatively large wing size.

In this paper, it can propose that Fuzzy Wavelet Morphology Neural Networks for the edge detection algorithm with being robustly a unclear boundary parts by brightness difference and being less sensitivity on direction to be detected the edges of images. This is applying the Fuzzy Wavelet Morphology Operator which can be simple the image robustly without the loss of data to DTCNN Structure for improving defect which carrys out a lot of operation complexly. Also, this color image can segment Y image with YCbCr space color model which has a lossless feature information of edge boundary sides effectively. This paper can offer the simulation of color images of 50ea for the performance verification of the proposal algorithm.

특정한 부분에 정확성을 가지는 기하학 형태인식은 이미지 분석 응용에서 중요하게 다루어져 왔다. 또한, 부분적 혹은 변형된 모양을 계층화하는 새로운 접근방법에 대한 연구가 계속되고 있다. 그러므로 본 논문에서는 자유형태의 부드러운 곡선을 생성하는데 용이한 스플라인 공식들을 이용하여 새로운 기하학 형태 매칭 접근 방법을 제안한다. 이와 같은 방법에서, 여러개의 스플라인 공식들로 생성된 곡선들의 집합은 동일한 형태의 성질을 가진다. 본 논문은 곡선 설계를 위하여 일반적인 상호작용 방법과 다양한 스플라인 공식간에 관계들을 이용함으로서 간단한 설계점(design point)들의 이동으로 형태매칭 방법에 관한 관계성을 보인다. 그러므로, 본 논문에서는 3차 스플라인의 공식(B-splines, Bezier splines, Catmull-Rom splines)을 이용하여 형태 매칭 방법을 제안한다.

관상학(Physiognomy)이란 사람의 얼굴을 보고 그의 운명, 성격, 수명 따위를 판단하는 방법을 연구하는 학문을 말한다. 이 논문에서 언급하는 관상학은 동양에서 말하는 관상학, 특히 얼굴의 부분적 특성이나 전체적인 조화를 통해 성격과 운영을 예측하는 학문을 의미한다. 이 연구는 동양 관상학을 적용한 성격별 얼굴 설계 시스템 구축에 관한 것으로, 첫째, 보편적인 성격 분류를 위해 MBTI에서 다루는 성격 어휘 161개를 군집분석을 통해 39개의 대표 어휘로 추출하였다. 추출된 대표 성격 어휘의 의미상 거리를 나타내기 위하여 서베이를 통해 얻은 데이터를 다차원 척도법을 통해 2차원 공간상에 성격 어휘의 관계를 분석하였다. 둘째, 얼굴 시각화를 위해 먼저 얼굴의 형태적 특성을 결정짓는 요소를 크게 얼굴형, 눈, 코, 입, 이마, 눈썹으로 분류하고, 분류된 6가지 얼굴 형태의 29가지 하위요소 별 성격을 한국인의 얼굴 특성을 기준으로 관상학적 정리 및 숫자형식 코드화를 하였다. 추출된 대표 성격 어휘별 얼굴 요소의 형태를 앞서 정리된 코드에 따라 하나의 얼굴 형태로 조합하여 39가지 얼굴을 시각화 하여 마지막으로, 성격별 얼굴 설계 시스템 'FACE'를 제작하였다. 이 연구는 사람의 성격 특성에 따라 그에 맞는 얼굴 형태를 구현하는 시스템을 제작하여 일반 사용자 뿐 아니라 애니메이션 캐릭터 개발자에게 객관적인 도움을 줄 수 있으며 또한 예로부터 내려오는 관상학의 적용 범위를 넓힐 수 있는 가능성을 보여주었다고 할 수 있다.
