چکیده
Aim: The aim of the study was to quantitatively assess effectiveness microneedle mesotherapy in reducing skin discoloration. results were analyzed using gray-level co-occurrence matrix (GLCM) method. Material and methods: forearm (7 × 7 cm) 12 women aged 29 68 examined. Microneedle performed a dermapen with preparation containing 12% ascorbic acid. Each volunteers underwent series four treatments. treatment quantified methods image analysis processing. A clinical images taken cross-polarized light before after cosmetic procedures. Then, treated areas by determining parameters algorithm: contrast homogeneity. Results: During pre-processing, volunteers’ separated into red (R), green (G) blue (B) channels. photos procedure show an increase brightness compared procedure. average 10.6%, decrease GLCM 10.7%, homogeneity increased 14.5%. Based on analysis, greatest differences observed during tests B channel RGB scale. With contrast, postoperative 0.1 noted, which is

Rock Texture Retrieval Using Gray Level Co-occurrence Matrix
Nowadays, as the computational power increases, the role of automatic visual inspection becomes more important. Therefore, also visual quality control has gained in popularity. This paper presents an application of gray level co-occurrence matrix (GLCM) to texturebased similarity evaluation of rock images. Retrieval results were evaluated for two databases, one consisting of the whole images an...
متن کاملTexture Based Image Retrieval Using Framelet Transform–Gral Level Co-Occurrence Matrix(Glcm)
This paper presents a novel content based image retrieval (CBIR) system based on Framelet Transform combined with gray level co-occurrence matrix (GLCM).The proposed method is shift invariant which captured edge information more accurately than conventional transform domain methods as well as able to handle images of arbitrary size. Current system uses texture as a visual content for feature ex...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Volumetric texture analysis of DCE-MR images of the breast using gray-level co-occurrence matrix method
Introduction Texture analysis using 2D-image-based gray level co-occurrence matrix method [1] has been demonstrated to be useful in distinguishing between malignant and benign breast lesions in contrast-enhanced MR images [2]. 2D texture analysis does not take advantage of the 3D data in breast MR images and requires high signal-to-noise ratio, which may not be available in dynamic studies. We ...
متن کاملPlant Recognition using Stereo Leaf Image using Gray-Level Co-Occurrence Matrix
Adequate knowledge, such as information about the unique characteristics of each plant, is necessary to identify plant. Researchers have made plant recognition based on leaf characteristics. The leaf image-based plant recognition in view of different angles is a new challenge. In this study, the research on the plant recognition was conducted based on leaf images resulted from 3D stereo camera....
