Effective and efficient fruit detection is considered crucial for designing automated robot (AuRo) for yield estimation, disease control, harvesting, sorting, and grading. Several fruit detection schemes for designing AuRo have been developed during the last decades. However, conventional fruit detection methods are deficient in the real-time response, accuracy, and extensibility. This paper proposes an improved multi-task cascaded convolutional network-based intelligent fruit detection method. This method has the capability to make the AuRo work in real time with high accuracy. Moreover, based on the relationship between the diversity samples of the dataset and the parameters of neural networks’ evolution, this paper presents an improved augmented method, a procedure that is based on image fusion to improve the detector performance. The experiment results demonstrated that the proposed detector performed immaculately both in terms of accuracy and time–cost. Furthermore, the extensive experiment also demonstrated that the proposed technique has the capacity and good portability to work with other akin objects conveniently. the chloroplast is responsible for providing the green colour in the plant. Where is the chromoplast its various types of colours in the plant.there is a change from Green to yellow colour in most of the fruit. This is due to the overgrowth of the chromoplast by replacement of the chloroplast hence there is feeding of the green colour and prominence of the yellow colour. The change of colour of unripe green fruit from green to red is because of the transformation of chloroplast to chromoplast because in immature stage chloroplast is green in colour while on maturation the chloroplast disappears and chromoplast containing carotenoids which impart red colour.
