Good and bad Classification of moringa flower or drumstick flower ( Moringa oleifera)

Fragrant, yellowish-white flowers of Moringa oleifera are the blooming parts of that tree belonging to Moringaceae family.
Appearance: They grow in large, drooping panicles and are about 1–1.5 cm long and 2 cm broad. Each flower has five unequal, thinly veined petals.
Nutritional Value: The flowers are rich in potassium, calcium, and amino acids, making them a valuable dietary supplement, especially for nursing mothers.
Edibility: They are considered a delicacy in many cultures, particularly in South Asia, where they are used in curries, fritters (pakoras), and teas.
Shelf life: Fresh moringa flowers are highly perishable. When stored in an airtight container in the refrigerator, they typically keep for a couple of days to approximately 7 days, depending on their initial freshness and moisture content.Fresh white-greenish flowers turn pale, yellow, or light brown as they age. Petals lose turgidity, wither, and eventually fall off.
Sample Collection:
Fresh and mature flowers of moringa tree are collected during the peak flowering season, generally in the of march from local trees of Malda,West Bengal, India ( 24°59'N to 88°08'E ) and the collection location was mapped using GPS coordinates .
Immediately after collection of samples, they were checked for presence of any dust particles and their removal. Bad ones are removed and good flowers separated from the bunch , isolated, placed on white and black A4 sheets . Digital images of the samples were captured using a smartphone (Xiaomi Redmi 12 C) operating on Android version 12 . This device was equipped with MediaTek Helio G85 (Up to 2.0GHz), 6GB RAM and 128GB internal storage.
Image acquisition was carried out daily for 5 consecutive days after collection to monitor the visual quality changes and shelf life deterioration. Approximately 250 images were captured per day over both white and black background, out of which 200 high quality images of each background, per day were selected based on clarity and focus .
The image dataset was used to study progressive changes in color, texture, surface integrity and microbial spoilage during storage.
In this dataset , 500 good image within "good" folder and 500 bad images within "bad" folders are included within the folder " white background. Same folders with similar numbers of images were included within another file named " black background. Therefore, total 2000 images of moringa flowers were uploaded in this dataset .

辣木科（Moringaceae）辣木树（Moringa oleifera）的淡黄色芳香花朵为该树种的开花器官。外观：该花呈大型下垂圆锥花序状生长，长约1–1.5厘米，宽约2厘米；每朵花具五枚形态不等、带有细脉纹的花瓣。营养价值：辣木花富含钾、钙与氨基酸，是极具价值的膳食补充剂，尤其适用于哺乳期女性。可食用性：在诸多文化中，辣木花被视作珍馐，尤以南亚地区为甚，常被用于咖喱料理、炸菜饼（pakoras）与茶饮的制作。保质期：新鲜辣木花极易变质。将其置于密封容器中冷藏保存时，视初始新鲜度与含水量差异，通常可保存2天至约7天。新鲜的白绿色花朵随存放时间延长会逐渐变为浅黄或浅棕褐色；花瓣会失去膨压、萎蔫，最终脱落。样本采集：在盛花期（通常为印度西孟加拉邦马尔达（Malda）地区的3月），采集当地辣木树上的新鲜成熟花朵，采集点位通过GPS坐标标记，地理范围为24°59'N至88°08'E。采集样本后立即检查并清除花朵表面附着的灰尘颗粒，剔除劣质花朵，将优质花簇分离分装，分别放置于白色与黑色A4纸上。使用搭载安卓12（Android 12）系统的小米Redmi 12 C智能手机进行样本数码成像：该设备搭载MediaTek Helio G85处理器（最高主频2.0GHz），配备6GB运行内存与128GB内置存储。采集后连续5天每日进行图像采集，以监测存储过程中辣木花的视觉品质变化与保质期劣化情况。每日在黑白两种背景下各拍摄约250张图像，每日依据清晰度与对焦质量，各筛选出200张优质图像。本图像数据集用于研究存储过程中辣木花的颜色、纹理、表面完整性与微生物腐败的渐进式变化。本数据集包含："white background"文件夹内设有"good"子文件夹（含500张优质图像）与"bad"子文件夹（含500张劣质图像）；"black background"文件夹内亦设有对应数量图像的同名子文件夹。本数据集总计包含2000张辣木花图像。
