Classification of Signals01:30

Classification of Signals

556
In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...

Plant Breeding and Biotechnology

19.5K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Aggregates Classification01:29

Aggregates Classification

350
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Classification of Systems-II01:31

Classification of Systems-II

183
Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Classification of Systems-I01:26

Classification of Systems-I

221
Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

How Data are Classified: Categorical Data01:11

How Data are Classified: Categorical Data

34.2K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Area of Science:

  • Agricultural Science
  • Computer Vision
  • Data Science

Background:

  • Soybean quality assessment is crucial for agricultural economics.
  • Automated classification systems require large, diverse datasets.
  • Existing datasets may lack sufficient variety in seed quality defects.

Purpose of the Study:

  • To introduce a comprehensive dataset of individual soybean seed images.
  • To facilitate research in automated soybean classification and quality assessment.
  • To provide a benchmark for image-processing algorithms in agriculture.

Main Methods:

  • Collected and curated a dataset of over 5000 soybean seed images.
  • Classified seeds into five categories: Intact, Immature, Skin-damaged, Spotted, and Broken.
  • Utilized an image-processing algorithm for segmenting individual seeds with >98% accuracy.

Main Results:

  • A dataset containing over 1000 images per category across five distinct soybean seed quality grades.
  • Successfully segmented individual soybean seeds (227x227 pixels) from larger images (3072x2048 pixels).
  • Demonstrated high segmentation accuracy (>98%) for individual soybean seeds.

Conclusions:

  • The presented dataset is valuable for training machine learning models for soybean quality assessment.
  • This resource can advance the development of automated agricultural inspection systems.
  • The dataset supports further research into image analysis for crop quality evaluation.
