| 摘 要： | 针对解密一个加密图像耗时长的问题，基于混沌帐篷映射加密算法提出一种图像加密预览算法。算法首先采用图像识别与图像分割技术选择图像关键区域或采用图像缩略图技术生成原图像的预览图像；然后利用混沌帐篷映射加密算法分别对原图像及其预览图像进行加密；最后将加密后的原图像和预览图像进行整合生成加密图像。该算法在解密原图像前先解密预览图像，实现加密图像预览功能。实验表明，该算法可以对加密图像进行解密前预览，预览效果好，耗时短。

| Abstract: | In order to solve the problem of long time to decrypt an encrypted image, an image encryption preview algorithm based on chaotic tent map encryption algorithm was proposed. Firstly, the algorithm used image recognition and image segmentation technology to get the image region of the original image or used the key technology to generate thumbnail images of the original image. Then, using the image encryption scheme based on chaotic tent map respectively encrypted the original image and preview image. Finally, integrating the encrypted original image and preview image generated encrypted image. Before decrypting the original image, the algorithm decrypted the preview image to realize the preview function of the encrypted image. Experiments show that the algorithm can preview the encrypted image before decryption, and the preview effect is good and short time consuming. |
