Definitions
- Pseudo-holographic images are determined in the prior art from at least two source images, wherein a first position, from which the first source image is taken, differs from further positions from which further source images are taken.
- the selection of the first image analysis point from a plurality of first pixels is done line by line.
- the invention discussed here solves the problem of the lack of image quality of the pseudo-holographic image in such a way that the method according to the invention comprises the following steps for each selected image analysis point:
- a first surrounding area is defined around the selected first image analysis point in the first original image, which is variable and adaptive in function of the first original image.
- the formation of the surrounding areas can be done by modifying the shape of the surrounding areas and / or creating new surrounding areas based on an assignment of geometric, partially nested shapes, such as rectangles, each containing image analysis points.
- An adaptation of the surrounding areas can be carried out in such a way that the surrounding areas are scaled.
- the adaptation of the first surrounding area and / or of the second surrounding area to, for example, the image information of the first original image or second original image can be carried out by methods such as segmentation methods, which are analogous to the methods for mesh generation for calculations according to the finite element method.
- a second environmental region is determined, which correlates with the first environmental region.
- One possible condition for searching the second environment area may be that first and second Surrounding area congraded or similar in terms of properties of the surrounding area.
- the second image analysis point is subsequently determined, which correlates with the first image analysis point.
- the inventive method is by no means limited to the fact that the image analysis points are determined line by line.
- the method steps described above allow the selection of the image analysis points to be carried out according to further methods known to the person skilled in the art, for example as a function of changes in the pixels taking place in the case of films.
- the method according to the invention can be distinguished by assigning properties such as size as a function of image information values such as gray tones, hues, structures of the first original image and / or the second original image to the first surrounding area.
- the method according to the invention can also include "assigning properties to the second surrounding area as a function of image information values such as gray tones, hues, structures of the first original image and / or the second original image.”
- a structure of an image becomes a feature within the image
- Grays and hues can analogously be image information values of an image
- the properties of the surrounding areas are assigned based on the image information values, which may include, for example, a surrounding area over an area having different structures, for example (for example, several trees of a forest) or the limitation of Surrounding areas are given by the image information.
- the assignment of the properties can, for example, be carried out in such a way that a certain property such as size is assigned to the surrounding area as a function of color intensity distributions, of a contrast course.
- the method according to the invention can be supplemented by assigning properties to the first surrounding area as a function of properties of at least one adjacent surrounding area of the first original picture and / or depending on characteristics of at least one surrounding area adjacent to the surrounding area surrounding the correlating analysis pixel.
- properties to the second environment region as a function of properties of at least one adjacent environmental region of the second original image and / or depending on properties of at least one environmental region adjacent to the environmental region surrounding the correlating analytical image point.
- the method according to the invention can extend to determining parameters for generating a pixel of the pseudoholographic image from the first pixel and / or from the second pixel based on the assigned properties of the first surrounding region and / or the assigned properties of the second surrounding region.
- the method according to the invention may comprise routines which cause the first surrounding area to comprise at least one first pixel of the first original image and / or the second surrounding region to comprise at least one second pixel of the second original image.
- a surrounding area extends over a region of the first original image or of the second original image with pixels of the same or similar content, then it may be useful to combine these pixels in a surrounding area around an image analysis point.
- the pixels are assigned the properties which correspond to those of the relevant image analysis point or are modified to the properties of the relevant image analysis point.
- a surrounding area comprises only the relevant image analysis point, no further relevant pixels.
- the method according to the invention may also comprise method steps for selecting the image analysis points with reference to the circumstance that a surrounding area may comprise at least one pixel, with a selection of the first image analysis point and / or the second image analysis point depending on the properties of the first surrounding area.
- a selection of the first image analysis point and / or of the second image analysis point takes place as a function of the properties of the second surrounding region.
- the further first or second image analysis point outside the first or second surrounding area from the relevant pixels
