image analysis and image segmentation methods are a current field of computer vision and are applied in many fields. This text deals with image segmentation and defining the leading edge of a color sample. For the experiment, a sample of material printed with process inks and their overprint was used. The printed material is a glossy white paper with primary print process colors Magenta and Yellow. The paper presents the methodology and procedure of image segmentation using the separation of colors into halftone values. From that values, this basic threshold is created and defined. A convulsion mask was used, the maximum target threshold of the given color was obtained from this basic halftone threshold, and its values were defined. Methods of image analysis of color originals offer the potential for use in the field of protection against forgery of works of art, especially in the area of graphic art techniques and their specific areas.

This paper presents the development of a low-cost, multi-spectral stereo-imaging system designed for autonomous farming applications. With the growing interest in reducing manual labor in organic farming through technological means, especially in tasks such as weeding and plant health monitoring, there is a significant push towards the development of autonomous robotic systems. These systems often rely on advanced imaging techniques for accurate plant identification, health assessment, and navigation. We propose a novel stereo-camera system combining RGB and near-infrared (NIR) imaging to generate Normalized Difference Vegetation Index (NDVI) images for detailed plant health analysis. The system utilizes off-the-shelf components, including a StereoPi board and RaspberryPi 4 compute module, equipped with two IMX219-160 cameras. By removing the NIR blocking filter from one camera, we achieve a dual RGB and NIR imaging capability, enhancing plant-to-soil contrast and improving the detection sensitivity crucial for automated weeding applications. Our approach includes system calibration, stereo-disparity computation, and NDVI image formation, demonstrating the feasibility of stereo-matching between RGB and NIR images through semi-global matching. Preliminary results indicate that the system is capable of producing NDVI images with reasonable quantitative values, offering insights into plant health that could significantly benefit autonomous farming operations. Improved contrast is observed in the NIR band, promising improved robustness of AI-based plant detection algorithms. Further studies will explore the system's potential in automated plant health and growth assessment, as well as its integration into robotic weeding and harvesting systems.
