1. Applicability of computer vision in seed identification: deep learning, random forest, and support vector machine classification algorithms
ABSTRACT The use of computer image analysis can assist the extraction of morphological information from seeds, potentially serving as a resource for solving taxonomic problems that require extensive training by specialists whose primary method of examination is visual identification. We propose to test the ability of deep learning, SVM and random forest algo

2. Follicular Lesions with Papillary Nuclear Characteristics: Differences in Chromatin Detected by Computerized Image Analysis
ABSTRACT Objective: Follicular lesions of the thyroid with papillary carcinoma nuclear characteristics are classified as infiltrative follicular variant of papillary thyroid carcinoma-FVPTC (IFVPTC), encapsulated/well demarcated FVPTC with tumour capsular invasion (IEFVPTC), and the newly described category “non-invasive follicular thyroid neoplasm with p

3. El análisis de imágenes como herramienta de monitoreo en la deshidratación de rodajas de banana
Abstract The objective of this work was to evaluate the morphometric, fractal and color changes during the dehydration of banana slices through the use of image analysis. The convective drying was performed between 75 °C and 134 °C at an air velocity of 0.65 m s-1. Results showed that the images provided quantitative information of the morphometric changes

4. COMPARATIVE ASSESSMENT BETWEEN PER-PIXEL AND OBJECT-ORIENTED FOR MAPPING LAND COVER AND USE
ABSTRACT: The traditional per-pixel classification methods consider only spectral information, and may be limited. Object-based classifiers, however, also consider shape and texture, firstly segmenting the image, and then classifying individual objects. Thus, a Geographic Object-Based Image Analysis (GEOBIA) was compared in conjunction with data mining techn

5. Image segmentation and particles classification using texture analysis method
Introduction: Ingredients of oily fish include a large amount of polyunsaturated fatty acids, which are important elements in various metabolic processes of humans, and have also been used to prevent diseases. However, in an attempt to reduce cost, recent developments are starting a replace the ingredients of fish oil with products of microalgae, that also p

6. Washing treatment impact on print quality of screen printed knitted fabrics
ABSTRACT The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics

7. Optimization of image analysis techniques for quality assessment of whole-wheat breads made with fat replacer
The cellular structure of healthy food products, with added dietary fiber and low in calories, is an important factor that contributes to the assessment of quality, which can be quantified by image analysis of visual texture. This study seeks to compare image analysis techniques (binarization using Otsu’s method and the default ImageJ algorithm, a variatio

8. Texture analysis of masses in digitized mammograms using Gleason and Menhinick diversity indexes
INTRODUCTION: Breast cancer is the second most common type of cancer in the world, being more common among women and representing 22% of all new cancer cases every year. The sooner it is diagnosed, the better the chances of a successful treatment are. Mammography is one way to detect non-palpable tumors that cause breast cancer. However, it is known that the

9. Nuclear entropy, angular second moment, variance and texture correlation of thymus cortical and medullar lymphocytes: Grey level co-occurrence matrix analysis
Análise da matriz de co-ocorrência de níveis de cinza (GLCM) é um método matemático bem conhecido para a quantificação das propriedades estruturais das células e tecidos, incluindo homogeneidade, complexidade e nível de desordem. Recentemente foi demonstrado que esse método é capaz de avaliar as mudanças estruturais finas do núcleo que, de outr

10. Caracterização da displasia fibrosa em imagens de tomografia computadorizada helicoidal empregando a análise da lacunaridade / Characterization of fibrous dysplasia in helical computed tomography images employing the analysis of lacunarity
Fibrous dysplasia is an alteration of development characterized by replacing normal bone for dense connective tissue and immature trabecular bones, typically found in teenagers and young adults. Genetic modification which involves alpha-Gs protein appears to be the basis of the process. The exact incidence and prevalence are difficult to be established, but

11. Comparação entre mapas de solos obtidos pelos métodos convencional e digital numa área complexa / Comparison between soil maps obtained by conventional and digital methods in complex area
Soil maps are essential for the development of agricultural areas in an economically viable and environmentally friendly manner. So far, Brazil only has soil maps of small scale (1:250,000 to 1:1,000,000), whose use is limited to agricultural and environmental planning at the farm. Despite its importance, in Brazil a few mappings have been carried out by pub

12. Qualidade da carcaça e da carne de caprinos de diferentes idades da Região das Palmas - Alto Camaquã. / Carcass and Meat Quality at different ages of goats of Region Palmas - Alto Camaquã.
The region known as Territory "Alto Camaquã" in the State of Rio Grande do Sul is distinguished by the preservation of a landscape on which an extensive cattle ranching has been consolidated over the years. This activity is reflected in the current context as a high dependence on renewable natural resources. Thus, one could envisage an opportunity for the r
