“…Because the indoor and outdoor form of architectural space does not belong to the standard fractal in the mathematical sense, the existing measurement methods are difficult to find the optimal random fractal coverage. In the actual measurement, when the size of the measured object is too large or too small, the coincidence between the measured body and the fractal body is not ideal, and the scale relationship between the measurement scale and the corresponding measure cannot well reflect the fractal dimension value, which makes the indoor and outdoor form of the building space actually have fractal properties only on a certain scale, and this continuous scale corresponding range is called the scale-free area [16], also known as the scale area. In order to better determine the fractal structure of the measurement region, it is necessary to select the scale-free region of the measured box dimension.…”

The three-dimensional organic growth features of buildings have been given more and more attention according to the unique view representation regulations of the indoor construction industry, in order to optimize the usage and allocation efficiency of building space. To explore the configuration structure of building function space, the three-dimensional box dimension algorithm is used to measure the fractal dimension of the indoor and outdoor form of building space, and the two-dimensional and three-dimensional fractal characteristics of building space are compared and analyzed; the method of the second derivative is utilized for the automatic recognition of fractal scale-free areas, aiming at the imprecise problem of the artificial judgment of scale-free areas in earlier fractal research of interior and outdoor forms of architectural space. The experimental results show that the second derivative method can effectively and automatically identify the scale-free region. The coefficients of linear fitting are above 0.990, and the indoor and outdoor forms of architectural space have clear fractal characteristics. After applying the method, the three-dimensional fractal dimension grows, indicating that the interior and outdoor form usage of architectural space in this area is generally effective and compact.

“…In the current CGH-based 3D object encryption technology, the 3D object is coded to generate CGH. Subsequently, the CGH is encrypted using 2D image encryption [18][19][20][21][22][23]. Kong et al [18] combined CGH with chaotic random sequences for hierarchical encryption of 3D objects.…”

“…The final decrypted message can only be obtained with full authorization. Han and Shen [20] employed a phase iteration algorithm grounded on angular spectral domains in order to encode CGHs as three pure phase functions to accomplish the encryption process. This approach enhances the capacity of encrypted information and diminishes the loss of information transmission.…”

A method is proposed to enhance the security of three-dimensional (3D) objects through computer-generated hologram (CGH) encryption and hiding. The process begins by encoding the 3D object using an iterative angular-spectrum layer-oriented method to create an optimized phase-only CGH. Next, the encrypted image is produced by modulating the phase-only CGH with a chaotic random phase mask (CRPM) generated through Henon mapping. Subsequently, a combination of discrete wavelet transform (DWT) and singular value decomposition (SVD) is utilized to embed the encrypted data into a visually secure image, ensuring the encryption and concealment of 3D objects. During decryption, the accurate decryption procedure and keys must be applied to achieve the final reconstruction. The utilization of CGH in conjunction with CRPM effectively enhances the security of 3D objects, while the integration of DWT and SVD ensures the visual security properties of the encrypted data, providing a dual layer of protection for 3D objects. Experimental simulation results demonstrate that this approach achieves high-security encryption and concealment of 3D objects, ensuring high-quality decryption of 3D objects during the reconstruction process.
