“…Additionally, typical image analysis techniques are employed to identify lesions and fundus characteristics, color grading, vascular segmentation, microaneurysm and hemorrhage identification, optic disk and macular localization, and the detection of hard exudates are only a few examples. [7]. There are several ways to identify HEs; one of them, with a SE of 92.8%, involves morphological reconstruction approaches.…”

Diabetic retinopathy causes blindness in diabetics. Early identification and frequent screening of diabetic retinopathy can slow disease progression and visual loss. Retinal lesions result from diabetic retinopathy. Dark and brilliant retinal lesions predominate. Color, shape, and size distinguish lesions. Exudates are bright, while microaneurysms (MAs) and hemorrhages (HEMs) are dark. This study presents a retinal lesion screening method for diabetic retinopathy. The data is saturated at low and high intensities; picture intensity values are adjusted to enhance contrast. This study presents a unique rhombus multilevel retinal image segmentation method. In the proposed study, preprocessing, segmentation algorithms, morphological operation,median filter and gradient are all designed as parts of an effective automated system. With 40 photos, the recommended method produced accuracy and specificity of 99.9% and 99.5%, respectively.

This work aims to manufacture photodetectors from semiconducting bilayer materials of zinc oxide Nanorods (ZnO NRs) and coated with a thin layer of CdZnS by chemical bath deposition method (CBD). The effect of annealing time on the optical and electrical properties of the prepared devices and on the parameters of the devices was also studied. The prepared films were thermally treated by annealing at a temperature of 200 ° C for several times for the purpose of comparison. The annealing times were 15 30 35 60 minutes, respectively, by means of a vacuum furnace. The effect of the annealing time was noticeable and obvious on the optical and electrical properties of the manufactured photodetectors.
