The proposed method enables users to adjust the compression rate according to application areas by applying small blocks to the more detailing area (non -stationary regions) and larger blocks to the background or less details area (homogenous regions) [1]. This proposed method “Mean Adaptive 3D-DCT” is applied on Holoscopic 3D images also known as Integral Images. In addition, the experiment results prove the method is applicable to any 3D content.

INTRODUCTION HIS compression standards aim to reduce the bitrates in order to store or transmit files. Widely known compression standards such as JPEG and MPEG uses DCT due to its ability to compact energy however DCT’s major drawbacks that it has blocking artifacts. In addition there is another issue related to the Blocking technique, which is the lack of inter-block correlation, which means each block is isolated from the other blocks. Therefore each block is treated separately by applying the microcosm technique. Intensive research has been carried on 2D images to avoid or alleviate the blocking artifacts and the attempt is made to find a solution for the miss correlation between the blocks [1]. There are two types of transform method that have been applied to resolve the errors that are Global Transform technique (non-Local) e.g. DWT, Lapping Transform and Local technique based on Blocking but in an adaptive manor. As stated, using the Global technique e.g. DWT which is applied in JPEG2000 works efficiently in reducing the blocking artifacts, however it is still facing a ringing artifact, which is due to the long basis. In particular, the areas have lots of edges. In addition, the method fails to exploit the local correlations in the areas with low frequency in the background of the image, which leads to improper compression ratio [2]. So, briefly there is a trade between the ringing artifacts and the blocking artifacts, either to have a ghost affect that will appear on the edge of the image or it will appear as a pre-echo in the case of audio or to have a visual discontinuity effect [3]. II. INTEGRAL IMAGES The three dimensions Display technologies can be categorized to two main categories, the stereoscopic display and auto- stereoscopic display [4] [5]. The main idea of the stereoscopic display based on combining two simultaneous images to be received by the two eyes and combined in the human brain to give the effect of the three- dimension effect. This technology can be achieved by using anaglyphs, which is Color-based filtering, or Polarization or Shutter-based filtering. The stereoscopic Display Technology suffers from causing headache and sickness because it depends on the brain to gather both images together which results of visual fatigue. On the other hand, in auto-stereoscopic display Technology there is no need to wear any glasses, and the technology doesn’t depend on the receiver eye or the brain to combine any images. The auto-stereoscopic display technology contains the holographic three- dimensional display techniques, Integral Photography and Lenticular Sheet 3D Images [4]. 3D Holoscopic methodology imaging also referred to, as Integral Images [6] was first proposed by Lippman in 1908 [7]. During the last few decades the Integral images developed by various researches. A glass or a plastic sheet consisting of Adaptive 3D-DCT based compression algorithms for Integral Images A.
