What is an autostereogram?

Autostreogram, also referred to as one image stereogram, or sis, is a picture created using computer graphics that deceives the brain into the perception of three -dimensional or 3D, when browsing two -dimensional or 2D, image. Common types of autostereograms that include random dots and wallpapers. 2D optical illusions creating an in -depth effect can usually be seen using specific focusing techniques. Instead of looking at the image itself, the viewer must use the viewer to detect a hidden image.

In a typical 2D image, colors, lines and overlapping images, they create the illusion of depth by means of perspective. Lighter colors bring the object forward and lines that are closer at one point, they seem to travel to a distance. Eyes also perceive depth when objects are strategically placed in front of them using a light to dark color gradient. Autostereogram of random dots or wallpaper uses technical techniques ofiques creates a 3D image.

random dot autostereogram with the bestRiva discovers millions of small dots or pixels. Dots can be black and white or highly colored. Texturing layers can also be added. Hidden inside these dots is a design, object or word, originally produced in gray gradient. This is generally a black and white image using lighting, shading and rendering to form a multidimensional image.

Using the stereogram program, the artist combines two pictures. Through camouflage, the boundaries of the Greyscale image are slightly changed by color compared to the surrounding dots or pixels, but the colors in the whole picture correspond to the background.

Wallpapers by autostereograms use a similar technique, with the exception of the 2D image generally contains repeated patterns, strategically placed horizontally or vertically at different distances. Combine artists color display with Greyscale and Greyscale image is slightly different from the surrounding colors. View throughThe Yta image contained in the autostereogram of random or wallpaper involves changing the visual focus line.

normally, when the individual looks at the picture, each eye perceives an image from a slightly different angle. The brain receives this information, creates a compound single picture and transmits information back to the eyes. Recognition of hidden images in autostereograms generally requires a change in point of focus from the image to a point around the stereogram. This type of changed focus is commonly referred to as a wall monitoring. Changing the focal point in this way is similar to viewing the window for viewing the scenery on the other side, where the brain eventually detects and reveals a closer image.

3D Cross -eye view includes two similar images placed side by side. For the brain that perceives depth, the viewer must change the focus from the pictures to the area in front of the picture that intersects the eyes. This focus combines the first two pictures and forms a third, creating the illusion of depth.
