This allows to correctly take into account the shape of the restoration area and not capture unnecessary boundaries that can lead to incorrect image reconstruction.Step 1: Download an Android emulator for PC and Mac The pixel p ∊ ( i, j) with the maximum priority value max( P( δS i,j)) at the border δS is determined, and the adaptive region ψ p belonging to this pixel is selected ( Figure 5). Considering the confidence factor C( δS) allows us to assign less weight to the reconstructed pixels as the distance from the available pixels from the area S increases. Initially, it is assumed that the value of the confidence factor C for pixels from area S is 1, and for area η is 0.Ĭalculating the priority using expression (1) allows you to give more weight to the pixels that are on the brightness differences (boundaries), thus restoring them in the first place. Where: δS i,j - current pixel at the border of available pixels C( δS)- the coefficient of confidence D( δS) - gradient coefficient Ψ δS - adaptive block of pixels centered at pixel δS i,j | Ψ δS|- the number of pixels of the adaptive block - a vector orthogonal to the gradient at point δS i,j n δS - a vector orthogonal to the boundary δS at point δS i,j. The article presents an approach based on a multimodal image inpainting algorithm using similar blocks with quaternions and anisotropic gradient. In this regard, it is an urgent task to restore both texture and structure of images. When recovering large areas with lost pixels, known techniques result in blurred images. Still, using these methods requires a significant amount of a priori information about the image. Most image reconstruction methods can be classified into the following groups based on geometry, edges, and exemplars methods. Therefore, they aren’t well suited for filling in areas far from the boundary. There are many existing inpainting models, but they tend to propagate local information into the unknown region. Automatic restoration of damaged or missing pixels is an image reconstruction problem from many practical applications, such as retouching digital photographs, restoring images, image coding, computer vision, etc. Image inpainting aims to restore a missing (damaged) area of “empty” pixels regions in a visually plausible manner using information outside of the damaged domain. Image inpainting and, in general, image reconstruction are significant problems in image processing. There are various digital processing methods used to solve the problems of recovering partially lost images. It is possible to solve this problem with the help of image reconstruction methods.Īn example of a depth map with missing regions.
As a result, the effect of overlapping objects appears, which makes it impossible to distinguish one object from another, or an increase in the object’s boundaries (obstacles) occurs. This problem occurs due to poor lighting, mirrored surfaces of objects, or the fine-grained surface of materials, making it impossible to measure depth information. A problem with all depth mapping methods is the presence of lost areas ( Figure 1). To build a map of the environment, we need to know the distance from the robot’s initial position to the obstacle. This method allows to build a map in a completely unfamiliar space for further use in planning the trajectory of movement. This uses simultaneous navigation and mapping techniques known as SLAM. In modern mobile robots, technologies are used that make it possible to build the most optimal path for its movement. Compared with state-of-the-art techniques, the proposed algorithm provides plausible restoration of the depth map from multimodal images, making them a promising tool for an autonomous robot navigation application. Moreover, the color information incorporates into the optimization criteria to obtain sharp inpainting results. We propose an algorithm using the concepts of a sparse representation of quaternions, which uses a new gradient to calculate the priority function by integrating the structure of quaternions with local polynomial approximation - the intersection of confidence intervals). We also perform depth completion by fusing data from multiple recorded multimodal images affected by occlusions. The proposed approach uses the modified exemplar-based technique in quaternion space. This paper presents an automated pipeline for processing multimodal images to 3-D digital surface models. In most cases, such a scene contains missing holes on depth maps that appear during the synthesis from multi-views. Automatic 3-D recovery from multimodal images can be extremely useful for information extraction for the robot navigation application.
