Additionally, the adaptive gain mechanism in infrared cameras leads to variations in the illumination across different viewpoints. These all can result in potential failures when utilizing infrared images for reconstructing Neural Radiance Fields (NeRF). To address these issues, we propose an end-to-end framework for pose estimation and rendering optimization. Specifically, perceptual pose optimization is used to estimate more accurate camera pose. To enhance the matching accuracy of multi scene corresponding points, we retain high-confidence camera poses while jointly optimizing both the scene and low-confidence poses. This allows for high-quality 3D scenes with accurate pose estimation for infrared images. The high-frequency-invariant attention module is designed to focus on the high-frequency features not easily captured and invariant edge information in infrared images by densely sampling, which can use high-frequency region to compensate for the low-frequency region differences caused by the adaptive gain mechanism. We evaluated our approach on datasets consisting of near-infrared, mid-wave infrared, and long-wave infrared images.

Simultaneously, the values of the original pixels (refer to “seed pixels”) are unchanged that serve for the extraction. Remarkably, the extraction process does not require a reference image, accurately retrieving both the embedded messages and the original image. The embedding procedure divides the cover image into 4 × 4 blocks. Within each block, four seed pixels remain unchanged, serving as references for recovering both the secret data and the cover image. Before embedding the data, the Multi-layer Center Folding Strategy (MCFS) encodes the secret data to minimize distortion. This strategy offers flexibility by allowing dynamic adjustments to the data embedding rate and Peak Signal-to-Noise Ratio (PSNR).

However, the KF based on CBC sampling points uses the minimum mean square error (MMSE) criterion, which can lead to significant estimation bias in the presence of non-Gaussian noises. To address this issue, this paper first proposes a novel Cauchy–Gaussian maximum mixture correntropy Kalman filter with component-by-component construction (CGMCKF-CBC) by the designed novel Cauchy–Gaussian maximum mixture correntropy (CGMC). Unlike the traditional maximum mixture correntropy criterion (MMCC), the CGMC uses the mixture of Cauchy kernel and Gaussian kernel as the cost function, and updates the posteriori estimates by the form of fixed-point iteration. Next, to further address the parameters selection issue existing in CGMCKF-CBC, an adaptive optimization strategy is proposed to determine appropriate parameters, resulting a variable CGMCKF-CBC (VCGMCKF-CBC).

Furthermore, the recovery of the CP factors is an ill-posed problem. One way to circumvent this limitation is to exploit the equivalence between the CPD and the Tensor Train Decomposition (TTD).
