“…Therefore, we think this may be a good direction for researchers in the future. Last, although designing decoding-related art is not a difficult task for graphics researchers, only a few works [ 6 , 8 , 22 , 65 ] exist. This may be because those artists rarely create this type of art, and researchers often follow the artists’ designs.…”

Visual arts refer to art experienced primarily through vision. 3D visual optical art is one of them. Artists use their rich imagination and experience to combine light and objects to give viewers an unforgettable visual experience. However, the design process involves much trial and error; therefore, it is often very time-consuming. This has prompted many researchers to focus on proposing various algorithms to simplify the complicated design processes and help artists quickly realize the arts in their minds. To help computer graphics researchers interested in creating 3D visual optical art, we first classify and review relevant studies, then extract a general framework for solving 3D visual optical art design problems, and finally propose possible directions for future research.

“…So decryption is performed by exploiting the human visual system without any complex computations which is an advantage that overcomes the disadvantage of pixel expansion where the size of the revealed secret image is not the same as the size of the original one. Several studies used visual cryptography as a security scheme for encrypting images in a simple way that can be later decrypted using vision [2] - [11]. Some studies concentrate on black and white images and others on color images [12][13][14][15] [16].…”

Enhanced Technique in VC With Four Meaningful Cover Images

Visual cryptography is an important technique for data hiding. In Visual cryptography (VC), a secret image is divided into multiple number of shares. Shares are distributed among multiple recipients, which makes it impossible for hackers to extract secret data from one share without having the other shares and thus data communication becomes secured. The secret data can only be disclosed by human eyes through stacking some or all of the shares. In this paper, we proposed a new image hiding technique that is based on VC. We embed a secret color image in four meaningful cover color images that have the same size as the secret image. The decryption method we used in our technique does not need previous knowledge of cryptography or complex computations thus maintaining the privilege of VC. The secret image can be retrieved if an acceptable number of cover images are stacked, otherwise; the original image retrieved may suffer from distortion and the required quality may not be achieved.According to our experimental results, our technique guarantees better quality of the retrieved secret image without pixel expansion and with less storage used as well as offering higher level of security.
