Image enhancement techniques have become more popular among the researchers as it is widely been used in security and medical applications. There have been different image enhancement technique approaches and filters were developed to enhancement the fingerprint images. While analysis a few accesses are established in spatial domain, frequency domain and fuzzy model. These techniques are based ...

Speech enhancement employing Deep Neural Networks (DNNs) is gaining strength as a data-driven alternative to classical Minimum Mean Square Error (MMSE) enhancement approaches. In the past, Observation Uncertainty approaches to integrate MMSE speech enhancement with Automatic Speech Recognition (ASR) have yielded good results as a lightweight alternative for robust ASR. In this paper we thus exp...

Background: Breast cancer is one of the most significant health problems in world. Early diagnosis breast very important for treatment. Image enhancement techniques have been used to improve captured images quick and accurate diagnosis. These include median filtering, edge enhancement, dilation, erosion, contrast-limited adaptive histogram equalization. Although these many studies, their result...

The delivery of medications through the skin has long been a fascinating as well difficult subject study. For different medications, topical drug administration brought substantial benefits over systemic route, one most important which is reduced toxicity due to minimal or no exposure non-target organs. Because its simplicity and affordability, preferred method for delivering medicinal substanc...

Image enhancement which is one of the significant techniques in digital image processing plays important role in many fields. Image enhancement improves the visual appearance of an image or to convert an image to a form better suited for analysis by a human or machine. Contrast enhancement is one of the commonly used image enhancement method to improve the quality of image. In this paper, adapt...

Image enhancement plays an important role in vision applications. Enhancement is the technique of improving the superiority of a digital stored image. Recently much work is performed in the field of images enhancement. Many techniques have already been proposed up to now for enhancing the digital images. In this paper, we have compared three basic techniques of the image enhancement which are h...
