Face detection is a challenging task in image processing field. Now days face detection is used in many application which requires identification and verification. The major application areas of face detection are biometric field, crowd surveillance, photography and many security related areas. Issue with face detection is that it should perform well in any condition such as illumination, color...

Compressive light field photography enables acquisition using a single sensor by utilizing color coded mask. This approach is very cost effective since consumer-level digital cameras can be turned into simply placing mask between the and aperture plane. paper describes deep learning architecture for compressive with Color Filter Array (CFA). Unlike previous methods where fixed pattern used, our...

PURPOSE To describe ultra-widefield fluorescein angiography (UWFA) findings in eyes with white without pressure (WWOP) and in eyes without any obvious peripheral chorioretinal disease, and to determine if a difference exists between these two groups. METHODS A retrospective review of 379 eyes undergoing diagnostic UWFA using the Optos 200Tx imaging system. Eyes were excluded if the quality of...

In food photography, factors like the camera angle, background, lighting, light color, and decorative elements are commonly manipulated to motivate consumption through impression of deliciousness. Studies have demonstrated these factors’ relevance on several subjects related perception. Nevertheless, effect that might deliciousness remains unclear. Therefore, comprehend visual perception, this ...

Different digital cameras have different spectral sensitivities and opto-electronic conversion functions (OECF’s), and therefore produce different data about the same scene. Correct interpretation of the data requires that it be presented in some sort of standard form. The most rigorous way to do this is to provide the raw data along with the camera color channel OECF’s and spectral sensitiviti...

Inkjet printing of photographs using both dye-based and pigmented inks has become the most popular form of hardcopy output from digital camera files. In addition to desktop and wide-format applications, inkjet printing technology is now also being adopted for “dry” minilabs and by professional portrait and wedding photography studios. Various factors affecting both light-induced and thermally-i...

Several systems have been developed to document lens opacities photographically. In general, the settings for these photographs have been standardized, but there has been no scientific basis for the selection of these settings. We investigated several of these variables. We examined the effect of degree of angulation of the slit beam in slit photography of the nucleus and found no difference in...

Color is the human sensory perception triggered by a portion of the electromagnetic spectrum commonly called light. Mechanisms for capturing and reproducing these perceptions can trace their origins to four events. First, Newton’s deduction that “white light” was a mixture of rays able to induce the sensation of color in a human. Some 140 years later Young offered a physiological explanation fo...

BACKGROUND Various imaging modalities play a role in diagnosing parasitic infections of the eye. We describe the spectral domain optical coherence tomography (SD-OCT) findings of an intravitreal parasite with subsequent evaluation by light microscopy. FINDINGS This is a case report of a 37-year-old Ecuadorian man who presented with uveitic glaucoma and a new floater in his left eye for 1 week...
