Can we use low resolution (60 m) images to get material classification accuracy close to that of 15 m resolution? The goal is to improve HyspIRI imager performance by using advanced software algorithms.

Image Processing – Research and Training in the Laboratory of Biocybernetics University of Mining and Metallurgy (AGH) in Krakow1996 •
Presented paper is a kind of "snapshot" of research and training activities in the Laboratory of Biocybernetics working in University of Mining and Metallurgy (now AGH University of Science and Technology). This Laboratory was one of the first Polish scientific groups working in Image Processing, therefore Editor in Chief of a newly created (in 1995) International Journal entitled "Image Processing &Communications" asked author for such comprehensive presentation of this Laboratory.

We present a dataset of close range hyperspectral images of materials that span the visible and near infrared spectrums: HyTexiLa (Hyperspectral Texture images acquired in Laboratory). The data is intended to provide high spectral and spatial resolution reflectance images of 112 materials to study spatial and spectral textures. In this paper we discuss the calibration of the data and the method for addressing the distortions during image acquisition. We provide a spectral analysis based on non-negative matrix factorization to quantify the spectral complexity of the samples and extend local binary pattern operators to the hyperspectral texture analysis. The results demonstrate that although the spectral complexity of each of the textures is generally low, increasing the number of bands permits better texture classification, with the opponent band local binary pattern feature giving the best performance.
With the increasing application of steel materials, the metallographic analysis of steel has gained importance. At present, grain size analysis remains the task of experts who must manually evaluate photos of the structure. Given the software currently available for this task, it is impossible to effectively determine the grain size because of the limitations of traditional algorithms. Artificial intelligence is now being applied in many fields. This paper uses the concept of deep learning to propose a fast image classifier (FIC) to classify grain size. We establish a classification model based on the grain size of steel in metallography. This model boasts high performance, fast operation, and low computational costs. In addition, we use a real metallographic dataset to compare FIC with other deep learning network architectures. The experimental results show that the proposed method yields a classification accuracy of 99.7%, which is higher than existing methods, and boasts computat...
