Retinal images and vessel trees play a crucial role in aiding ophthalmologists to identify and diagnose various illnesses related to the eyes, blood vessels, and brain. However, manual retinal image segmentation is a laborious and highly skilled procedure, posing challenges in terms of both difficulty and time consumption. This study proposes a novel approach to retinal image segmentation, leveraging the Denoising Diffusion Probabilistic Model (DDPM) for precise performance. To our best knowledge, DDPM is being applied in this domain for the first time. Our approach incorporates a novel constraint to prevent DDPM from generating vessel structures that not present in the original retinal images during the segmentation process. Additionally, our model is not limited to the original DDPM size of 64 x 64 pixels. Instead, we train it to effectively segment images sized 256 x 256 pixels. This is a significant advancement since the original DDPM works exclusively with 64x64 image sizes and is primarily designed for generating random image samples. In our work, we address both limitations with a novel, efficient approach for accurate retinal image segmentation. A comprehensive evaluation of our methodology includes both quantitative and qualitative assessments. Our proposed method demonstrates competitive performance compared to state-of-the-art techniques, as indicated by both qualitative and quantitative scores.

Object-based image analysis (OBIA) is extensively used for the classification of High-Resolution Satellite imagery (HRSI). The various attributes of the image segments like spectral, spatial and textural, can be generated for analysis and classification purposes. However, the use of all these attributes may not lead to attaining high classification accuracy. Experiments have shown that, a suitable set of these features need to be identified for faster and accurate classification of imageries. The filter based methods likeChi-Square, Information-gain and ReliefF are extensively used for identification and ranking the best set of parameters. The random tree based Boruta machine learning feature ranking method is also used in identifying the feature ranking along with the above algorithms. Subsequently, a learner is fused with a filter and the resultant receiver operating characteristic (ROC) plot of the model has been used to identify the best accuracy and the minimal set of attributes for identifying an individual feature like roads, trees, grass, buildings and shadow. The best set of parameters for a class is identified by the best ROC plot. The best parameters are identified from Boruta feature analysis. The results indicate that the identified smaller feature set helps in enhancing classification accuracy.

In recent years, with the continuous development of society, people's exploration in the field of machinevisionimages has gradually increased the demand for machinevision and digital imageprocessing. Only the consistency comparison research of machinevisionimages based on the improved ORB algorithm, in order to obtain more complete image information. Based on the improved ORB algorithm, this paper conducts research by improving the consistency comparison of machinevisionimages, and meets the requirements of accuracy and precision for the obtained machinevisionimages and so on. This paper briefly introduces the technology and development trend of machinevisionimage consistency comparison, studies the machinevisionimage consistency comparison, and through a series of experiments to prove that the machinevisionimage consistency comparison based on the improved ORB algorithm is effective in To a certain extent, it has certain feasibility in terms of precision and accuracy. Analysis and comparison based on different image stitching methods were carried out. The final results of the research show that the accuracy of the five-consistency comparison of machinevisionimages is 98.7% when the distance of image five is 83.4 km. Experimental data show that the accuracy of machinevisionimage consistency comparison has always been maintained at a stable level, that is, 97%. It shows that the accuracy of machinevisionimage consistency comparison does not decrease with the increase of distance.

We propose a computer vision architecture based on Hyperbolic networks, contrastive learning and knowledge distillation to detect unsafe behavior in energy production and oil & gas plants. Data scarcity poses a significant challenge to develop machine learning applications in industry. Indeed, the data may be incomplete, inconsistent, or biased, making it difficult to develop accurate and reliable models. Insufficient data during training phase has direct impact on the models' representation learning capabilities;with the aid of vision Transformers (ViTs), we are able to solve data crunch situations by learning efficient representations of the existing data. We harnessed the power of ViTs, as it incorporates more global information, leading to quantitatively stronger intermediate feature representations. Further, we approached the task with contrastive learning and obtained pairs of samples which are similar, to tackle the limited data availability in our industrial use case. The proposed approach by applying hyperbolic embeddings helps in extracting complex relationships in the data. Furthermore, the size of the model makes it suitable for devices with low computational capabilities such as unmanned robots.
