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. Arboreal Identification Supported by Fuzzy Modeling for Trunk Texture Recognition
RESUMO Devido à variabilidade natural da casca arbórea, há padrões de textura em imagens de tronco com valores pertencentes a mais de uma espécie. Logo, o presente estudo analisou o uso da modelagem fuzzy como uma alternativa para lidar com a incerteza no reconhecimento de padrões, em comparação com outros algoritmos de aprendizado de máquina. Para

3. An Empirical Evaluation of the Local Texture Description Framework-Based Modified Local Directional Number Pattern with Various Classifiers for Face Recognition
ABSTRACT Texture is one of the chief characteristics of an image. In recent years, local texture descriptors have garnered attention among researchers in describing effective texture patterns to demarcate facial images. A feature descriptor titled Local Texture Description Framework-based Modified Local Directional Number pattern (LTDF_MLDN), capable of enco

4. Taxonomic indexes for differentiating malignancy of lung nodules on CT images
Abstract Introduction Lung cancer remains the leading cause of cancer mortality worldwide, with one of the lowest survival rates after diagnosis. Therefore, early detection greatly increases the chances of improving patient survival. Methods This study proposes a method for diagnosis of lung nodules in benign and malignant tumors based on image processing

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. Comparative leaf anatomy and morphology of some Brazilian species of Crotalaria L. (Leguminosae: Papilionoideae: Crotalarieae)
Anatomical characters often provide strong taxonomic evidence and many times help define species whose morphological limits are in question. This study aimed to survey characters of the leaf anatomy of 16 species of Crotalaria L. occurring mostly in the cerrado (savanna) of central Brazil and in areas of restinga (coastal woodland, or sandy forest) along the

7. ESTUDO DE ÍNDICES DE DIVERSIDADE COMO DESCRITORES DE TEXTURA PARA CLASSIFICAÇÃO DE IMAGENS DE FACES / STUDY OF DIVERSITY INDICES AS DESCRIPTORS OF TEXTURE FOR CLASSIFICATION IMAGES OF FACES
O objeto de estudo deste trabalho é uma investigação sobre o potencial grau de caracterização de texturas de faces humanas em imagens digitais usando índices de diversidade. Para isto é desenvolvida uma metodologia que utiliza o retinex como técnica de normalização de iluminação, índices de diversidade para a extração de características e a M

8. Sistema de visão artificial para identificação do estado nutricional de plantas / Artificial vision system for plant nutricional state identification
A avaliação do estado nutricional das plantas de milho usualmente é feita através de análises químicas ou pela diagnose visual das folhas da planta, esta última, sujeita a erros de interpretação já que a ausência de algum nutriente na planta gera um padrão de mudança específico na superfície da folha que depende do nível de ausência do nutri

9. Desenvolvimento de um Sistema de Auxílio ao Diagnóstico de Pneumonia na Infância Utilizando Visão Computacional / Development of a System of Aid to the Diagnosis of Pneumonia in Children Using Computer Vision
This work aims to develop a system to aid in the diagnosis of pneumonia by computer, termed pneumocad, which aims to identify chest radiographies compatible with the disease. Techniques were used for the recognition of patterns in textures through the decomposition of the wavelet transforms of the features extracted from the decomposition and classification

10. Um algoritmo de segmentação de íris em tempo real / An iris segmentation algorithm in real time
Iris segmentation is one of the crucial operations involved in iris recognition. Accurate iris segmentation is fundamental for the success and precision of the subsequent feature extraction and recognition, and consequently the high performance level of the iris recognition system. Most iris segmentation approaches proposed in the literature require highly c
