We specifically target to detect faint astronomical sources which value near the image background level. Our main directions include Mathematical Morphology (MM) and Convolutional Neural Network (ConvNet). The contributions of this study are presented in two parts:The first part proposes a novel morphological-based approach based on component-graphs and statistical hypothesis tests. The component-graphs can efficiently handle multi-band images while the statistical hypothesis tests can identify components that are significantly different from the background level. Beyond the classical component-trees and their multivariate extensions, the component-graph holds the complete structural information of multi-band images as directed acyclic graphs (DAGs). Such DAGs are more general and more powerful at the cost of non-trivial object filtering algorithms. Then, we introduce two algorithms to filter duplicated and partial components in the component-graphs. Experiments demonstrate that our proposed approach significantly improves object detection on both multi-band simulated and real astronomical images.The second part turns our attention to ConvNet direction.We introduce a real dataset of annotated astronomical objects.Based on this dataset, we propose two models: a ConvNet-based model and a hybrid model. The ConvNet-based model tailors astronomical contexts with three novel components, including a normalization layer, an object differentiation module, and a smoothness regularizer. Besides, the hybrid model uses both Morphology and ConvNet. In the hybrid method, morphological modules select region proposals while ConvNet extracts relevant information from the selected proposals. Ablation studies show that the two proposed models outperform the state of the art on both synthetic and real datasets. Note de contenu : Introduction

La possibilité de cartographier les espèces dans la canopée par télédétection est d'un intérêt évident, tant appliquées que scientifique. Les inventaires spatialisés à l'échelle du paysage contribueraient à faire progresser les connaissances fondamentales de ce biome complexe et menacé et aiderait à sa gestion durable. Les cartes de distribution d’espèces peuvent être croisées avec les facteurs environnementaux et fournir ainsi des clés d’interprétation des schémas d’organisation des peuplements forestiers. Du point de vue de la gestion, les cartes de distribution des espèces offrent une rationalisation de l'exploitation forestière. La cartographie des espèces commerciales pourrait favoriser des pratiques forestières minimisant l'impact environnemental de l'exploitation. L'identification des espèces permettrait de prioriser les zones particulièrement riches en espèces commerciales, tout en évitant d'ouvrir des pistes d'exploitation dans les zones à faible niveau de ressources exploitables. La télédétection offre également la possibilité de surveiller l’extension des espèces proliférantes, telles que les lianes. Des capteurs hyperspectraux et LiDAR ont été utilisés à bord d’un avion pour identifier les espèces dans les forêts tropicales guyanaises. Une large gamme spectrale issue des capteurs hyperspectraux (400–2500 nm) est mesurée permettant d'avoir de nombreux descripteurs. Le LiDAR embarqué offre une description fine de la structure du couvert, facilitant la segmentation des houppiers. La fusion de ces deux informations améliore la caractérisation de la ressource. Afin de tirer le meilleur parti des données hyperspectrales, différents prétraitements radiométriques ont été évalués. Le lissage spatial et le filtrage des ombres sont les principaux facteurs qui améliorent la discrimination des espèces. L'utilisation de la gamme spectrale complète est également bénéfique. Ces résultats de classification ont été obtenus sur un groupe 20 espèces abondantes. L’identification de ces mêmes espèces en mélange au sein d’un peuplement hyperdiverse a constitué la deuxième étape de ce travail. Nous avons évalué le niveau d'information nécessaire et le degré de confusion tolérable dans les données d’apprentissage afin de retrouver une espèce cible dans une canopée hyperdiverse. Une méthode de classification spécifique a été mise en œuvre pour être insensible à la contamination entre classes focales/non focales. Même dans le cas où la classe non focale contient jusqu’à 5% de pixels de la classe focale (espèce à identifier), les classifieurs se sont révélés efficaces. La troisième étape aborde le problème de la transposabilité des classifieurs d’une acquisition à une autre. La caractérisation des conditions d’acquisition et la prise en compte de leurs effets sont nécessaires pour convertir les données de radiance en réflectance de surface. Cependant cette opération de standardisation reste une étape extrêmement délicate au vue des nombreuses sources de variabilité : état de l’atmosphère, géométrie soleil-capteur et conditions d'éclairement. Nous évaluons en comparant des vols répétés sur le même site, la contribution des diverses caractéristiques d’acquisition à la divergence spectrale entre dates. Ce travail vise à proposer des pistes pour développer des méthodes de reconnaissance d'espèces qui soient plus robustes aux variations des caractéristiques d'acquisition.

[Termes IGN] texture du solRésumé : (auteur) Surface soil water content (SWC) is a major determinant of crop production, and accurately retrieving SWC plays a crucial role in effective water management. Unmanned aerial systems (UAS) can acquire images with high temporal and spatial resolutions for SWC monitoring at the field scale. The objective of this study was to develop an algorithm to retrieve SWC by integrating soil texture into a vegetation index derived from UAS multispectral and thermal images. The normalized difference vegetation index (NDVI) and surface temperature (Ts) derived from the UAS multispectral and thermal images were employed to construct the temperature vegetation dryness index (TVDI) using the trapezoid model. Soil texture was incorporated into the trapezoid model based on the relationship between soil texture and the lower and upper limits of SWC to form the texture temperature vegetation dryness index (TTVDI). For validation, 128 surface soil samples, 84 in 2019 and 44 in 2020, were collected to determine soil texture and gravimetric SWC. Based on the linear regression models, the TTVDI had better performance in estimating SWC compared to the TVDI, with an increase in R2 (coefficient of determination) by 14.5% and 14.9%, and a decrease in RMSE (root mean square error) by 46.1% and 10.8%, for the 2019 and 2020 samples, respectively. The application of the TTVDI model based on high-resolution multispectral and thermal UAS images has the potential to accurately and timely retrieve SWC at the field scale.

[Termes IGN] pouvoir de résolution spectraleRésumé : (auteur) Pan-sharpening methods are commonly used to synthesize multispectral and panchromatic images. Selecting an appropriate algorithm that maintains the spectral and spatial information content of input images is a challenging task. This review paper investigates a wide range of algorithms, including 41 methods. For this purpose, the methods were categorized as Component Substitution (CS-based), Multi-Resolution Analysis (MRA), Variational Optimization-based (VO), and Hybrid and were tested on a collection of 21 case studies. These include images from WorldView-2, 3 & 4, GeoEye-1, QuickBird, IKONOS, KompSat-2, KompSat-3A, TripleSat, Pleiades-1, Pleiades with the aerial platform, and Deimos-2. Neural network-based methods were excluded due to their substantial computational requirements for operational mapping purposes. The methods were evaluated based on four Spectral and three Spatial quality metrics. An Analysis Of Variance (ANOVA) was used to statistically compare the pan-sharpening categories. Results indicate that MRA-based methods performed better in terms of spectral quality, whereas most Hybrid-based methods had the highest spatial quality and CS-based methods had the lowest results both spectrally and spatially. The revisited version of the Additive Wavelet Luminance Proportional Pan-sharpening method had the highest spectral quality, whereas Generalized IHS with Best Trade-off Parameter with Additive Weights showed the highest spatial quality. CS-based methods generally had the fastest run-time, whereas the majority of methods belonging to MRA and VO categories had relatively long run times.
