Digital Image Enhancer

Image enhancer?

In all of the cop shows on TV, they have an image enhancer for digital images, where they select a portion of an image, click a button and voila! the blurry image is now clear. I don't know if this actually exists or if its just tv magic, but does anyone know of a product available to the public?

well its tv they just show a blurry picture and then the real one you could clean it up by hand in photoshop or gimp but idk if there are any programs to do that

Digital Image Watermarking $106.74 The digital information age has evolved with numerous opportunities and new challenges. The goal of this book is to provide a framework based on watermarking techniques that can be used for verifying the integrity of a digital image along with the recovery of the intentionally or unintentionally distorted digital image. The efficient and hybrid techniques have been developed in this book which makes tradeoff between three contradicting properties of watermarking; imperceptibility, robustness, and capacity. The watermarking techniques given in this book are able to answer these questions, i) Has the image been processed? ii) Has the image been processed incidentally or maliciously? iii) Which part of the image has been processed and how much? Additionally, a selfrecovery approach makes it possible to recover the exact version of the host image even after the image has been incidentally or maliciously processed.

Natural Image Statistics in Digital Image Forensics $96.59 Over the past decade, with the increasing popularity of Internet and digital technology, images in digital format have become ubiquitous. At the same time, with the breakneck speeds of the development of technology that allows for digital images to be manipulated and distorted, detecting tampering or validating authenticity of digital images are of great importance for forensic practitioners. This book provides the first general framework, based on universal statistical properties of natural images, of detecting tampering and authenticating digital images that has been successfully applied to three problems in digital image forensics: (1) differentiating photographic images from computergenerated photorealistic images, (2) detection of steganography (hidden messages) in digital images; (3) differentiating lively captured and rebroadcast images in biometricbased authentication systems, and also to digital authentication and identification in art forensics. This book should help bridging the research work in image modeling and forensics, and should be especially useful to researchers and practitioners in image modeling, digital image forensics or related fields.

Digital Image Steganography $164.1 Steganography is the science of secret communication. It comes under the assumption that if the feature is visible, the point of attack is evident. This book investigates current stateoftheart methods and provides a new and efficient approach to digital image steganography. It also establishes a robust steganographic system called Steganoflage. Steganoflage advocates an objectoriented approach in which skintone detected areas are selected for embedding where possible. The key issues in this book are: 1) a new image encryption method tailored to digital images and steganography/watermarking, 2) a new, efficient and realtime skintone detection algorithm and 3) a new embedding method using the RBGC, in the Wavelet domain. Each of these components is tested against relevant performance measurements. A series of interesting contemporary applications are shown. This book is dedicated to digital image steganography, and is the cream of three years of focused work, presented in such a way to be the ideal companion for researchers both beginners and professionals. The simplified presentation allows researchers and students from other disciplines to grasp its essentials.

Lecture - 17 Image Enhancement

Digital Image Formats - JPEG, GIF, RAW .. What Do All These Mean?

We spend hours and hours, taking the best photographs we can, and when we're done - we apply special techniques to them with a special editing software to enhance what we've originally seen. When we are done, we try and save them in the correct format to preserve the image in the best way possible, but most people have no idea what the differences are.

The three main files a digital camera uses to store its digital images are JPEG, TIFF, and RAW formats. We need to understand what these digital image formats are and their properties - only then will we be able to get a high quality photograph.

The first format, and the one used in graphic design and photography quite often, is JPEG - a commonly used standard method of compression of images. In fact, the majority of photographers use this as their primary image mode. One of the main reasons is because it can be used right out of the camera with no editing, as it is considered a high-quality first use image. It also transfers easily across the Internet, and as email attachments. Plus it is fastest writer from the camera memory buffer to the memory card storage.

On the other side, it is not as sharp out of the camera as TIFF or RAW modes, and every time the JPEG is manipulated more than once or twice, it will eventually become unusable. But more than any of this, every time the JPEG image is modified and resaved, it will lose more data.

PEG stands for "Joint Photographic Experts Group", named after the joint committee which created it in 1986. The JPEG (file extensions are .jpg, along with .jpeg, .jfif, jpg., .JPG, and .JPE) format provides for lossy compression of images, which means that when data is compressed, and then decompressed, the data that is decompressed may be different than the original. Yet, it is sufficient to be useful in some way or another.

JPEG/JFIF is the format that is used when photographs are stored and transmitted on the Internet. It is preferably over GIF, which is limited to 256 colors that are not enough for colored photographs, or PNG, what produces larger image files.

But then, just as many photographers use TIFF as their primary usage. The TIFF is a file format used for storing images such as line art and photographs, developed by Aldus, now Adobe Systems, and Microsoft. A popular format for high color depth images, it is supported by many image-manipulation programs such as Pagemaker, QuarkXPress, Adobe InDesign, PhotoShop, Paint Shop Pro, etc. It is extremely high in its image quality, with excellent compatibility with the publishing companies.

Tiff can be modified and resaved, with the images being used an endless number of times without throwing away any image data. Plus the image is extremely usable, as it does not require software post-processing during or after its download from the camera. It is a flexible and adaptable , with an advantage of no picture loss, which makes it acceptable to the publishing industry.

Compared to the RAW format, it uses less storage space, and is suitable for changes from any photo-editing software. A big disadvantage is its very large file size, still choking small e-mail boxes. During photography shoots, memory cards are needed if using TIFF images, but more pictures can be taken with the same amount of memory space.

The RAW mode is a picture format where the camera has made absolutely no changes; the files are not yet processed or ready to use with an editor, etc. Not a whole lot of professionals use this mode, other than camera purists, or weird website article writers. In order for it to be manipulated, the image needs to be processed and converted to an RGB format that is either TIFF or JPEG. This means that each and every pixel that was captured by the camera is now on the image.

You can now download this image on your computer for processing. Its advantages are that a huge amount of control over the final look of the image is yours. Additionally, all original details stays in the image for any and all future processing needs.

However, when you do so you will notice that this is a very large image, probably a few MBs. This means that you will need a very large storage area or memory space if you are going to shoot images in RAW format. Your advantage is that you can sharpen, size, or crop the picture without losing any picture quality.

But your disadvantage is the file size. You cannot transmit it easily because it needs high bandwidth connections. Also, you can shoot very few photographs if you select the RAW mode. After that, you have to change the memory card or make space by erasing a few photographs. Also, this mode is generally not accepted by the publishing industry because it produces a 12-bit image. The photographer needs to modify it using photo-editing software before submitting it for publication.

Overall, if a photographer wants to keep all the original image data that was recorded, the image must be stored in RAW format. It is the closest thing that we will be able to see in a film negative or a transparency that the digital camera can make.
