Patterned graphene oxide one-step thermal annealing for controlling collective cell migration.

Graphene oxide (GO) is a two-dimensional metastable nanomaterial. Interestingly, GO formed oxygen clusterings in addition to oxidized and graphitic phases during the low-temperature thermal annealing process, which could be further used for biomolecule bonding. By harnessing this property of GO, we created a bio-interface with patterned structures with a common laboratory hot plate that could tune cellular behavior by physical contact.

Shoeprint retrieval: Core point alignment for pattern comparison.

Purpose: Shoeprint recognition has been widely used as forensic evidence in criminal cases. The purpose of this study is to propose a shoeprint retrieval method based on core point alignment for pattern analysis.

Method: The proposed method firstly detects contour points in a black-and-white shoeprint image.

Identification and segmentation of obscure pectoral muscle in mediolateral oblique mammograms.

Objective: X-ray mammography is a widely used and reliable method for detecting pre-symptomatic breast cancer. One of the difficulties in automatically computerized mammogram analysis is the presence of pectoral muscles in mediolateral oblique mammograms because the pectoral muscle does not belong to the scope of the breast. The objective of this study is to identify the boundary of obscure pectoral muscle in mediolateral oblique mammograms.

Reconstruction of Banknote Fragments Based on Keypoint Matching Method.

Banknotes may be shredded by a scrap machine, ripped up by hand, or damaged in accidents. This study proposes an image registration method for reconstruction of multiple sheets of banknotes. The proposed method first constructs different scale spaces to identify keypoints in the underlying banknote fragments.

Plant identification through images: Using feature extraction of key points on leaf contours(1.).

Premise Of The Study: Because plant identification demands extensive knowledge and complex terminologies, even professional botanists require significant time in the field for mastery of the subject. As plant leaves are normally regarded as possessing useful characteristics for species identification, leaf recognition through images can be considered an important research issue for plant recognition. •

Methods: This study proposes a feature extraction method for leaf contours, which describes the lines between the centroid and each contour point on an image.

Identification of breast contour for nipple segmentation in breast magnetic resonance images.

Purpose: The purpose of this study is to develop a method to simulate the breast contour and segment the nipple in breast magnetic resonance images.

Methods: This study first identifies the chest wall and removes the chest part from the breast MR images. Subsequently, the cleavage and its motion artifacts are removed, distinguishing the separate breasts, where the edge points are sampled for curve fitting.

The use of scale-invariance feature transform approach to recognize and retrieve incomplete shoeprints.

Shoeprints left at the crime scene provide valuable information in criminal investigation due to the distinctive patterns in the sole. Those shoeprints are often incomplete and noisy. In this study, scale-invariance feature transform is proposed and evaluated for recognition and retrieval of partial and noisy shoeprint images.

Detection and construction of chest wall on breast magnetic resonance images.

Purpose: The purpose of this study is to propose a method for detection and construction of chest wall for breast magnetic resonance images.

Methods: A volume of breast MR slices are firstly acquired and utilized to detect initial points of chest wall. To calibrate the chest wall curve, the points along the curve is set with reference to its neighboring points.

Estimation of breast density: an adaptive moment preserving method for segmentation of fibroglandular tissue in breast magnetic resonance images.

Purpose: Breast density has been found to be a potential indicator for breast cancer risk. The estimation of breast density can be seen as a segmentation problem on fibroglandular tissues from a breast magnetic resonance image. The classic moment preserving is a thresholding method, which can be applied to determine an appropriate threshold value for fibroglandular tissue segmentation.

Identifying prognostic factors for drug rash with eosinophilia and systemic symptoms (DRESS).

Drug rash with eosinophilia and systemic symptoms (DRESS) is a severe cutaneous drug reaction. Although the severity-of-illness score (SCORTEN) has been proposed for toxic epidermal necrolysis (TEN) for 10 years, a prognostic score for DRESS is still lacking. To identify prognostic factors of DRESS patients during hospitalization in one medical health system in Taiwan.

Mammogram retrieval through machine learning within BI-RADS standards.

A content-based mammogram retrieval system can support usual comparisons made on images by physicians, answering similarity queries over images stored in the database. The importance of searching for similar mammograms lies in the fact that physicians usually try to recall similar cases by seeking images that are pathologically similar to a given image. This paper presents a content-based mammogram retrieval system, which employs a query example to search for similar mammograms in the database.

Mammogram retrieval on similar mass lesions.

Enormous numbers of digital mammograms have been produced in hospitals and breast screening centers. To exploit those valuable resources in aiding diagnoses and research, content-based mammogram retrieval systems are required to effectively access the mammogram databases. This paper presents a content-based mammogram retrieval system, which allows medical professionals to seek mass lesions that are pathologically similar to a given example.

Sarcoidosis with cutaneous granulomatous vasculitis.

Ulceration of non-caseating granulomas is a rare cutaneous presentation of sarcoidosis. Granulomatous vasculitis is classically associated with Wegener's granulomatosis, lymphomatoid granulomatosis or Churg-Strauss syndrome. It is also commonly noted in pulmonary sarcoidosis, but has seldom been reported in cutaneous sarcoidosis, particularly the ulcerative variant.
