# A Novel Hybrid Edge Detection and LBP Code-Based Robust Image Steganography Method
###### Abstract
They also stored edge status information within image pixels, but that also suffers from poor visual quality. The scheme proposed in [15] overcame the drawbacks of [7; 8]. In that scheme, authors utilize the full embedding space without storing edge information. [PERSON] [10] proposed a novel edge-based image steganography method. The Canny edge detection technique is used by the author to identify and implant only edge pixels in this scheme. They simultaneously used the \(2^{k}\) correction approach to improve the image quality of stego images while encrypting the secret data using the Huffman encoding algorithm. The scheme suffers from poor embedding capacity due to the selection of edge pixels only. [PERSON] [11] proposed another image steganography method based on pixel value differencing (PVD). This scheme suffers from poor embedding capacity. [PERSON] et al. [12] proposed a true edge-based image steganography method. By utilizing a clever edge detection technique, they only choose edge pixels, and they use the LSB method to implant four bits of hidden information into each edge pixel. Along with having poor visual quality, this scheme also has weak embedding capability. [PERSON] et al. [13] proposed a new steganography scheme by combining irreversible and reversible methods. Their approach is based on pixel value difference (PVD), least significant bit (LSB) substitution, PVD shift, and change of prediction error (MPE). [PERSON] and [PERSON] [14] proposed a novel image steganography method based on edge detection and XOR coding. They implant secrets either in the spatial domain or transform domain of the cover image. The scheme of [3] combined cryptography and steganography algorithms. They encrypt the secret data using the Data Encryption Standard (DES) and implant using the LSB method on the edge area of the cover image, which is generated by the Canny edge detection algorithm. [PERSON] and [PERSON] [16] also combined cryptography and steganography algorithms. They use the chaotic approach to encrypt the secret data, and they implant it using LSB and variable-length data that is hidden on the cover image's edge and non-edge regions, which is produced by a fuzzy edge detector. The scheme of [17] proposed a novel image steganographic algorithm based on the canny edge detection algorithm and hybrid hamming codes. [PERSON] and [PERSON] [18] proposed another steganography method based on canny edge detection, dilation morphological operator, and XOR coding. [PERSON] et al. [20] proposed an image steganography based on the fuzzy edge detection method. They detect edge pixels using the fuzzy edge detection algorithm on a 2-bits cleared image and implant 2-bits secrets on selected edge areas using the LSB method. [PERSON] and [PERSON] [19] proposed another image steganography method based on hybrid edge detection and LSB method. [PERSON] [21] proposed an image steganography method based on the hybrid edge detection algorithm, the dilation morphological operator, and the LSB method. [PERSON] et al. [26] proposed an image steganography method based on the Kirsch edge detection algorithm and implant secrets into each triplet of pixels. The scheme of [22] proposed an image steganography method based on PVD and edge detection algorithm. [PERSON] et al. [23] proposed an image steganographic algorithm based on a logistic map for encrypting secret information and Laplacian of Gaussian (LoG) edge operator to find edge areas of the cover image. [PERSON] and [PERSON] [25] proposed an image steganography scheme based on hybrid edge detection and LSB method. [PERSON] et al. [39] proposed a reversible image steganography based on reduplicated exploiting modification direction, image interpolation, and canny edge detection algorithm. [PERSON] and [PERSON] [32] proposed a multi-layer data embedment scheme based on prediction error. The scheme of [40; 41; 42; 43] proposed a reversible image steganography algorithm. [PERSON] and [PERSON] [24] proposed an image steganography method based on local binary pattern (LBP).
